Understanding Aperture – A Beginner’s Guide

Aperture is one of the three pillars of photography, the other two being ISO and Shutter Speed. Without a doubt, it is the most talked about subject, because aperture either adds a dimension to a photograph by blurring the background, or magically brings everything in focus. In this article, I will try to explain everything I know about aperture in very simple language.

Before reading any further, I highly recommend reading about what a DSLR camera consists of.

1) What is Aperture?

Simply put, aperture is a hole within a lens, through which light travels into the camera body. It is easier to understand the concept if you just think about our eyes. Every camera that we know of today is designed like human eyes. The cornea in our eyes is like the front element of a lens – it gathers all external light, then bends it and passes it to the iris. Depending on the amount of light, the iris can either expand or shrink, controlling the size of the pupil, which is a hole that lets the light pass further into the eye. The pupil is essentially what we refer to as aperture in photography. The amount of light that enters the retina (which works just like the camera sensor), is limited to the size of the pupil – the larger the pupil, the more light enters the retina.

So, the easiest way to remember aperture, is by associating it with your pupil. Large pupil size equals large aperture, while small pupil size equals small aperture.

2) Size of Aperture – Large vs Small Aperture

The iris of the lens that controls the size (diameter) of the aperture is called “diaphragm” in optics. The sole purpose of the diaphragm is to block or stop all light, with the exception of the light that goes through the aperture. In photography, aperture is expressed in f-numbers (for example f/5.6). These f-numbers that are known as “f-stops” are a way of describing the size of the aperture, or how open or closed the aperture is. A smaller f-stop means a larger aperture, while a larger f-stop means a smaller aperture. Most people find this awkward, since we are used to having larger numbers represent larger values, but not in this case. For example, f/1.4 is larger than f/2.0 and much larger than f/8.0.

Take a look at this chart (image courtesy of Wikipedia):

F-numbers

The size of the circle represents the size of the lens aperture – the larger the f-number, the smaller the aperture.

3) What is Depth of Field?

One important thing to remember here, the size of the aperture has a direct impact on the depth of field, which is the area of the image that appears sharp. A large f-number such as f/32, (which means a smaller aperture) will bring all foreground and background objects in focus, while a small f-number such as f/1.4 will isolate the foreground from the background by making the foreground objects sharp and the background blurry.

Depth of Field

Image on left shot at f/2.8, Image on right shot at f/8.0

As you can see, just changing the aperture from f/2.8 to f/8.0 has a big effect on how much of WALL-E is in focus and how visible the background gets. If I had used a much smaller aperture such as f/32 in this shot, the background would be as visible as WALL-E.

Another example:

Mailboxes

Mailboxes - Aperture set to f/2.8

In the above example, due to the shallow depth of field, only the word “Cougar” appears sharp, while everything else in the front and behind of that word is blurred. If I had used a larger aperture such as f/1.4 and focused on one of the letters, probably only that letter would have been sharp, while everything else would have been blurred out. The larger the aperture, the smaller the area in focus (depth of field).

4) Lens Apertures: Maximum and Minimum

Every lens has a limit on how large or how small the aperture can get. If you take a look at the specifications of your lens, it should say what the maximum (lowest f-number) and minimum apertures (highest f-number) of your lens are. The maximum aperture of the lens is much more important than the minimum, because it shows the speed of the lens. A lens that has an aperture of f/1.2 or f/1.4 as the maximum aperture is considered to be a fast lens, because it can pass through more light than, for example, a lens with a maximum aperture of f/4.0. That’s why lenses with large apertures are better suited for low light photography.

The minimum aperture is not that important, because almost all modern lenses can provide at least f/16 as the minimum aperture, which is typically more than enough for everyday photography needs.

Nikon 50mm f1.4 AF-S

This 50mm lens has a max. aperture of f/1.4

There are two types of lenses: “fixed” (also known as “prime”) and “zoom”. While zoom lenses give you the flexibility to zoom in and out (most point and shoot cameras have zoom lenses) without having to move closer or away from the subject, fixed or prime lenses only have one focal length. Due to the complexity of optical design for zoom lenses, many of the consumer lenses have variable apertures. What it means, is that when you are fully zoomed out, the aperture is one number, while zooming in will increase the f-number to a higher number. For example, the Nikon 18-200mm lens has a variable maximum aperture of f/3.5-f/5.6. When zoomed fully out at 18mm, the lens has an aperture of f/3.5, while when fully zoomed in at 200mm, the lens has an aperture of f/5.6. The heavy, professional zoom lenses, on the other hand, typically have fixed apertures. For example, the Nikon 70-200mm f/2.8 lens has the same maximum aperture of f/2.8 at all focal lengths between 70mm and 200mm.

Why is this important? Because larger maximum aperture means that the lens can pass through more light, and hence, your camera can capture images faster in low-light situations. Having a larger maximum aperture also means better ability to isolate subjects from the background.

  1. I am getting my new Nikon slr this week after using a good point and shoot, I was wondering about getting that 55 lens since it is obviously part of the 18-200. I guess I wonder if I can do the macro closeup with blurred backround with this lens… or it is best to get the 55 so I can have more choices?

    Thanks so much for the tutorials, btw. They are really helpful to the novice!

    • Deana,

      Could you let me know what Nikon camera you are getting so that I could recommend the lenses for it? If you are getting any of the entry-level DSLRs, they typically come with a Nikon 18-55mm VR lens, which is an excellent lens for everyday use.

      For food photography though, I would recommend a different lens with a much larger maximum aperture. Take a look at this Nikon 50mm f/1.4 – we use it for our food photography and couldn’t be happier.

      When you take pictures of food, having a small area of the food in focus while having the rest blurred makes pictures and the food look much more pleasant to the eyes.

      Please let me know if you have any other questions.

        Nasim, thanks for taking the time to write all the newbie tips for taking pictures. I have one question please. I have a Canon SX40 HS and i would like to take a great picture of my sons graduation. When he is on stage and i am about 20 30 yards away, what is the best setting so my picture does not become dark? I bought this camera as it has 35x zoom.

        Any of your great input would be very much appreciated.

        Hi Nasim,

        I am a beginner at food photography and I have done a couple of assignments with my 50mm 1.8 lens. Would you rather that I trade my lens for the faster 1.4? Just curious. I have mostly shot in natural light and I have not felt the need to use a tripod (it restricts my angles, surely). But sometimes my focus goes awry.I mean I noticed a portion of the food would be in focus while the other not quite. Frustrates me. I feel I am not focussing right! Any tips for that?
        I also was wondering if there is a anywhere I could read about using light for food photography. That would be great. Asking for your recommendation cause I feel then I just can’t go wrong.
        Thanks a bunch.

        Cheers.

My interests are in Landscape and Wildlife photography, which I believe both require very different lenses.which lenses do you recommend? I currently own a Nikon D3200, do you think I would be better off with an FX format camera like the D600?

        I am doing clothing photography. I am using a white seemless background as all picture need to be in a total white background. I need the entire shirt to be in focus. This will be done sometimes on a model and other times using a mannequin. I am completely lost to get the best crispest pictures. I am using a Nikon D7000 camera.

    Very helpful. Thanks a lot.

    Just a question, when do we need smaller than 14..15.. etc “f” numbers ?
    Average f no’s in my photos are between 6 and 10. (apart from some macros)

    • Shams, you are welcome. When not using flash, smaller f-numbers are needed for two reasons:
      a) to decrease the depth of field (i.e. isolate subject from the background)
      b) to allow more light into the lens in low-light situations

    Nasim, after reading the article I was playing around with my Lumix FZ 35. I was trying to get a blurry background using Apperture priority mode but was not able to get one. Everything is in focus. I was using f2.8 and zoomed out all the way. What am I doing wrong?

    • Alisher, keep your aperture at f/2.8, get physically closer to your subject, then zoom in. Take a picture and your background should be blurred.

      The distance between you and your subject, along with the focal length of your lens are both important to be able to blur the background. The closer you are to the subject and the more zoomed in the lens is, the less the depth of field should be, resulting in background blur.

  4. 7
    ) Alisher

    Actually, I was shooting from realy small distance. I thought that in order to get a blurry background the lenses should be zoomed out all the way. I will try with zoom-in. Will let you know results.
    Thanks

    • Alisher, sounds good. Since you are doing this with a point and shoot, the background might not appear completely blurred, because the lens aperture will increase to a higher number as you zoom in. This is normal, since the only way to completely blur the background is to use fast aperture prime lenses on DSLRs…

  5. 9
    ) Alisher

    Yeah, I’ve noticed that aperture is increasing with zoom-in. The thing is that on specialized forums dedicated to this particular model I’ve seen a lot of pictures taken by FZ-35/38 with blurry background. I was just wondering what I am doing wrong. Last night I was able to get the background somewhat blurry, but as you said it was not complete blurry. Will keep playing around with aperture, may be need to go outside to shot same pictures – will see how it goes.

    You said that you mostly shoot in “aperture priority” mode. What principle do you use to change the aperture number? Thanks for all comments.

    PS. I’ve seen “Tesha akani o’gli” today, vspominali armiyu:)

    • Alisher, since the depth of field on point and shoot cameras is typically larger due to lens design, you need to make sure that there is nothing close in proximity to the object you are taking a picture of. The further the background, the more blurry it will appear. That’s probably why the background is not blurred – because it is very close to your depth of field.

      Can you post any of the samples from your camera with the best and worst case scenario?

      In terms of aperture priority mode, if your camera has that mode, set it to aperture priority, then set the aperture to the lowest number. That way the shutter speed will automatically be computed by the camera metering system. Once set to aperture priority mode, try pressing up/down buttons on the camera back to change aperture. I’m not sure how it is changed on your camera, but if those buttons don’t do anything, I would look at the manual and see how to change aperture of the lens.

    ) Alisher

    Background WAS very close to the object indeed, since I was shooting indoors at home. I will try to shoot some pictures outdoors.

    I already know what “apperture priority” mode means and how it works and I do have this mode on my camera. It is very handy to switch aperture using joystick. What I was asking for is what kind of situation or shooting object would be reason for you to change aperture, for example to increase it? Do I need to increase aperture only if I want larger depth of field?

    I will pass your regards to Sher when I see him next time.

    • Aha! That’s the reason why it didn’t get that blurred :) Definitely give it a try outside, but keep the aperture at the lowest number.

      In terms of increasing aperture – yes, you are right. You should increase the aperture to get a larger depth of field (when taking pictures of landscapes, etc).

    Hi Mr. Mansurov,

    I’ve read ur article since I was confused what type of dslr I have to bought. Now I had D90 for my first camera, & so happy to have it :p
    I want to ask about apperture priority that u’re using mostly to take a picture.
    I’m learning to use A-mode too in my D90, what i need to ask is when I want to take a picture in a room that have less light, which stop do u usually use?
    Because the shutter speed is so slow, & I got blurry images.
    FYI, I used 18-105 lens kit
    Thx b4

    • Steven, the above article should work for any DSLR, including your D90.

      When you photograph indoors or in a low-light environment, always decrease your aperture to the smallest number. That way, your aperture opens up and lets more light into the camera sensor and increases your shutter speed. For your 18-105mm lens, the aperture varies between f/3.5 and f/5.6, so try to keep it in that range.

      If you are still getting blurry images, try increasing your ISO to a larger number such as ISO 800 or 1600. You will get some noise in the pictures, but the images should not be blurry, depending on the amount of light in the room.

      Hope this helps.

    Hi Nasim,
    Thanks for the article. I need some advice on using macro lenses if you don’t mind :)

    I’m thinking of getting a Micro-Nikkor AFS 60mm for food photography. As the pictures I’m thinking of taking are unplanned (restaurants etc) and might be low light, I’m planning on taking the photos at f2.8 or at most f3.5 to maximise ambient light.

    I understand that for “real” macro photography, I need to stop down the aperture to get more DOF, or it’ll all end up looking blurry, but most probably I won’t be using 1:1 magnification for food shots.

    Mostly I should be shooting the dishes with some background, utensils etc, so do you think f2.8~f3.5 would be enough DOF, or would it be too thin? Thanks for any advice :)

    • gnohz, why are you planning to buy a macro lens for food photography? Why don’t you get a fast aperture lens like the Nikon 50mm f/1.4G instead? Lola shoots all of her food with the Nikon 50mm and she loves it!

      • 23
        ) gnohz

        Hi Nasim,

        Thanks for your reply.
        The reason for getting a macro lens is because sometimes I felt like taking some close up shots of the food and I find the minimum focusing distance to be somewhat limiting. And also apart from food, I also plan to take close ups of other subjects/still life :)

        Could you let me know what is the minimum f number you shoot for food so as not to get an overly small depth of field, but still able to shoot in slightly low light conditions (ie, indoors without flash)?

        Thanks so much for your advice.

        • I see :) In that case, the 60mm macro seems like a good candidate. For food photography, the apertures that work the best for us are between f/2.0 and f/4.0, depending on subject distance.

    Hi Nasim, Thank you very much for this guide. I just picked up the Nikon D5000 a couple of days back and totally lovin’ it ! So far as my reading goes, the Aperture mode seems to be the best way to play around with the settings than getting into pure play manual mode – at least from a dslr newbie point of view.

    Currently i am on the 18-55 VR lens and i hope to purchase the 35mm f1.8 lens once ive learnt how to use the camera properly.

    Thanks again.

      Congratulations with your purchase. Let me know if you have any questions.

        ) David

        Thank you for your reply Nasim. Ive been taking pictures through the weekend and have taken some good ones and some not so good ones. However, Ive been reading your site extensively and figured the first proper foothold I could get is work on the ” aperture ” mode, Auto ISO – Max it to 1600 and min shutter speed to 1/100 and then take pictures.

        the D5000 offers many other options – The scene mode , macro and so on… Im trying to find what can be used for what.

        Another major difficulty Ive seen is taking pictures in Low Light. But after reading from your site, i guess i have quite a lot to work on.

        I will come back with further questions. As of now, Its ‘A’ mode, ISO settings, Matrix metering and click pictures..

        D

        • David, yes, learn how to use Aperture priority mode and turn Auto ISO on to get started. Min shutter speed 1/100 is good for most situations, but bear in mind that if you need to freeze action, you will need to watch your shutter speed and perhaps even increase it.

          I wouldn’t worry about other modes, since all they do is tweak your aperture, shutter speed and ISO. In some cases they might change autofocus behavior, but you should just learn how to use those yourself and make changes manually. D5000 is a great camera to get started and once you learn all the functions, you can take some beautiful pictures with it.

          In terms of low light situations, most photographers have challenges, not just you :) I have written a long article on low-light photography, which I recommend to read and learn from. Try taking pictures in all kinds of situations – from very bright to very dark. That way you will quickly understand what works and what doesn’t and your learning experience will be less frustrating :)

            Thanks Nasim. I did just that.. I turned on the Auto ISO setting, set it to Max 1600 and the shutter to 1/100 and I immediately started noticing the difference.

            Yes, I have been reading your article on low light photography and find it immensely useful. I, however, need to work on the standing posture as i have noticed the shake.

            I am eager to learn as riding season starts soon and I wouldnt want to take blurry pictures of the places in riding to.

    Hello Nasim, i just love your articles, they are so helpful.
    My question is related to blurry images. i bought Canon eos 550d not so long ago and when i shoot pictures, some of them are crystal clear ( that is one out of 20 ) and rest of them are just a litle bit blurry, but enough to be bad. they look like person is moving little bit in a low light with low iso, but im shooting them on sunny afternoon. im getting blur pictures even with iso 800 or 1600. im shooting in AV mode and i would like to get pictures if its possible on iso 100, 200 or 400. if i put f to 3.5 im having problem with depth of field even on small distances ( 5 to 10cm ). im geting clear focus on one person, and other one is blurry ( even though they are standing next to each other ). is it possible that my Auto focus is not doing good job?
    i would appreciate if you could tell me how to make clear picture of my son with my wife holding him in her hands, and to make them both perfectly clear ( its not low light situation, its bright daylight shooting ). do i have to increase F and how much, and would EOS 550d do a good job on AV mode for that photo, and how much should my shooter speed be for clear photos. ( when i increase shooter speed, i need to pump up the iso, and i really hate the noise ).
    tnx alot,

    Sanny.

    • Sanny, what is the shutter speed when you shoot in AV mode? Just make sure that it stays fast enough to avoid motion blur.

      In terms of depth of field, just don’t stand too close to your wife and your son and shoot from a further distance. What lens are you shooting with?

  14. 36
    ) gnohz

    Hi,
    if I’m not wrong, I think your shutter speed is a little on the low side and that causes the blur. Are you shooting indoors? Even if it’s bright daylight, shooting outdoors and indoors does make a difference. Generally, a prefered shutter speed is 1/n where n is the focal length. So if you’re shooting at 50mm, the shutter speed should be at least 1/50 secs so as to minimise any hand shake.

    Hope this helps :)

    • 37
      ) gnohz

      Sorry, the above post was supposed to be meant for Sanny.

    • Thank you for your suggestion gnohz! I think his problem is that he is using a very small aperture like f/10 and is standing too close to his subjects, which is ultimately resulting in slower shutter speeds…

    ) Trisha

    I have a question. I have the Olympus E-420 and it has an Aperture mode on it. I am taking a photography class and cant seem to get my depth of filed right. When I tried it yesterday, it worked fine, but today it just keeps taking the same picture. I have read too many articles about this until I got sick on my stomach and got a headache. Can you please tell me what I am doing wrong? I have the kit lens which is a 14-42 lens and I bought a 70-300mm lens. I wanted to use my 70-300 for close ups to show the intensity. I am stuck and at a loss. I have to turn an assignment in and I do not know what to do at this point.

    • Trisha, your depth of field depends on the subject distance – i.e. how far you are standing from the subject. If you are standing very close, you will get more background blur (obviously you need to shoot at your maximum aperture such as f/1.4 or f/3.5). If you have a zoom lens, zoom in all the way to get as close to the subject as you can. If you stand far away, you subject will be out of your depth of field and the background will not be blurred.

      So, try this:
      1) Stand as close to the subject as you can
      2) Shoot at maximum aperture
      3) Zoom in all the way

      If your lens cannot focus, it means that you are standing too close. Move back a little and try again. And by the way, don’t try to produce bokeh with your 14-42 lens at 14mm. Use your 70-300mm instead.

      Hope this helps.

    By increasing aperture do you get a larger depth of field? …..do you mean by decreasing aperture (or increasing F-STOP) you get a larger depth of field?
    Can you clarify? I am fairly new to photography.

      I’m not trying to hijack the discussion, but you’re right. You need to close down the aperture (which is equal to increasing the f number) to get a larger depth of field :)

    • VJ, when I said “increase aperture”, I meant “increase f-number”. Yes, to get a larger depth of field, you need to stop down to a larger f-number.

    Appreciate some helpful pointers from u and recommended settings for white balance, and ISO.

    Hello Nasim,

    I recently stumbled upon your website and have enjoyed reading your articles thus far. I am new to photography and recently got my D90 + 18-55mm. I have read the manual and your Beginner’s Guides to ISO, Aperture…however, I am still at a loss as to where to start! Coming from a point-and-shoot, it suddenly seems like I have many variables to play with and although I can understand how each of those settings affect the photograph (from your guides), I have no idea how they should come together to make a great picture. I’d like your advice on how I should actually go about getting started with my camera [apart from shooting in Auto mode ;) ]. I have tried messing within each of the modes but all my pictures turned out worse than what I got with Auto mode; I must be doing something wrong somewhere and I hope you can lead me in the right direction.

    Hi Naseem,

    I am very new to DSLR world and have a basic DSLR for now (18-55mm/f3.5-5.6). I want to buy 50mm/f1.8. Also, at the same time I want a zoom lens as well (18-200mm). Let me know if I can use both the lenses together? Also, is there another lens that I should go for instead of buying two seperate lenses (one for wide angle and another for zooming).

    Appreciate your help,
    Mamta

    Hi Nasim,
    I am really hoping you still check this! I am really trying to understand aperture, but the one thing that keeps getting me is HOW a larger opening/aperture means LESS stuff, forward and back, that is in focus… and a smaller opening/aperture makes more things forward and back in focus… it just does NOT make sense to me.
    I would think a larger opening would give a lot more, in foreground and background, in focus. Why does it not?

    Also, I have the Nikon D5000 with the Kit lens (AF-S Nikkor 18-55mm 1:3.5-5.6G)
    Based on the last paragraph of this article I am a little confused – can I still take pictures that have a lower aperture?? Nevermind on this. I just played with my camera and realized that NO, I can only go as low as 3.5 or 5.6 depending on whether I am zoomed out or in respectively. Very interesting!

    I am asking all this b/c I am doing photography of infants and children and would like to not only be able to achieve a shallow depth of field, but also to UNDERSTAND it.

    Will an aperture setting of f/3.5 or f/5.6 still give me a shallow depth of field when doing children and infant photography? If not, what type of lens would you recommend??

    Thank you!!

    ) pragadeesh

    hello sir ,
    I’m so much interested in photography that I would like to know about aperture settings for zoom lens.
    There is also a setting like ‘point focus’, can it be possible to point focus on a subject by having more aperture? or achieve depth of field?
    Can the aperture be changed for a zoom lens the is set up to the maximum focal length?As you said that “……while when fully zoomed in at 200mm, the lens has an aperture of f/5.6″
    Just a question out of curiosity-Would this type of setting be helpful in focusing on the background rather than foreground ?
    And What does ‘G’ refer to in ‘f/1.4G’ ?
    I’m naive in photography and someone who hasn’t started eperimenting with the SLR(not owning one)…
    Thanks !

    Hi Nasim,

    Thank you very much for sharing your extensive knowledge with the rest of us.

    I was just wondering if you could recommend a good inexpensive lens for indoor portraits. I’m trying to capture my 4.5 yo daughter with 18-55 kit lens on D5100 Nikon and results are passable but not very impressive. Also could you maybe post a listing of default settings that you would use on DSLR such as max ISO, WB offset, max/min f stop etc. that you would use for 90% of the time, meaning daily photography of kids family parties for both indoors and outdoors environments. Scene modes are great but one of the reasons I have SLR is to have more control of my settings vs letting computer make all the decisions.
    Thanks again for a great site.

    Hi! I have a Canon Rebel T3i EOS 600D which came with a Canon Zoom 18-55mm 1:3.5-5.6 IS II lense.
    I am wanting to increase the blurred background on my portraits of people, bugs, etc. am thinking of purchasing the EF 100mm f/2.8L Macro IS USM. Is that a good idea? the best idea?
    how much of an increase would I see in the blur? I don’t want the camera shake – so am interested in lenses that have the IS option, but am not sure if I am going to see much of a difference in the blur for the amount of money I’ll be spending on the 2nd lense. please advise.

      ) Mayowa Obigbesan

      For people portraits, if you already own the EF 50mm f/1.4, you should be fine getting blurred backgrounds. A point of note is that the subject should be quite distant from the background.

      For Macro Photography, I will advise you invest in a good tripod and and not rely on the IS function of the lens you purchase.

      I suspect you don’t have the EF 50mm f/1.4 lens and you are thinking the EF 100mm f/2.8L Macro IS USM will cater to both portraits of people and bugs. On this note, I am curious as well.

      I hope I have helped you some.

      Hi Mayowa, I am still absolutely confused about DOF ! The alternate between aperture numbers and aperture. What affects DOF? What makes a large Or small DOF ? What causes blurry background?

      • 160
        ) Mayowa Obigbesan

        Hi Olumide,

        Are you familiar with the Canon 50mm f/1.8 II prime lens? I would like to use it as an example in aiding me answer your questions.

        1a. This lens has f/1.8 as its maximum aperture ‘value’ and f/22 is its minimum aperture ‘value’; the smaller numbers apparently represent higher aperture values.

        1b. At its max. aperture value (f/1.8), the aperture (lens opening) will be wide open, which allows in a lot of light. Whereas, at its min. aperture value (f/22), the aperture (lens opening) will be really small, which allows in less light. I’m sure you’ve experienced how this affects your shutterspeed i.e. faster shutterspeeds at max. aperture value against slower shutter speeds at min. aperture value.

        2. At its max. aperture (f/1.8), it will have the smallest DOF (area that is sharp and in focus) and at its min. aperture (f/22), it will have the largest DOF ( a wider area that is sharp and in focus).]

        3. At its max. aperture (f/1.8), since the DOF is small, your subject will be in focus and the background will be blurry; provided that there is adequate distance between your subject and the background. At its minimum aperture (f/22), the focus area is wider and therefore your subject and his/her/its background will all be in focus. Nothing will be blurry irrespective of the distance between your subject and the background.

        I hope I have answered your questions adequately. If there’s more you’d like to know, feel free to send a reply.

        Best regards

What I mean is that my flash was up but doesn’t seem to be working even thou it is on. I also am having a problem with I guess it would be my shutter speed. When I take a picture no matter where I am at or what setting (I really like the child setting right now) It clicks to take the picture then its about 7-10sec before it actually takes the pic…I am not sure if this has something to do with the flash or not! The pictures come out blurry and infocused…i am so frustrated b/c I dont know how to fix it let alone where to begin! I reset the camera just on a whim and that did nothing. Also even though the flsh is up it clicks everytime I am getting ready to take a pic like it is popping up? I am sorry I may not be making much sence but this is the best way I can describe it!

    Hi Nasim,

    I own a Nikon D5100 for over 6 months now. I have 18-55 VR kit lens and Tamron 70-300 macro lens. I am planning to add 50 F1.8 lens to my arsenal. But things start getting confusing from here on.
    There are 2 versions of the same lens available from Nikon, G and D. With the G version costing almost twice of that of D. Although the D version would not auto focus on my camera I am perfectly all right with that. Also would get the aperture ring with the D version, which would help me with the extension tubes and lens reversal. I would like to know if there are any major differences as far as the image quality is concerned, so that I should spend double the amount and go for the G version.

    I haven’t been able to figure out how to get the expected ‘blur’ results from my 18-105VR Kit lens.
    I try pressing the DoF button. It produces a loud click sound but i don’t get any different results.
    Is this because the camera won’t support it, of does this have to do something with the capability of the lens ?
    And what lens should I invest in, in order to get the desired blur results, like the ones you’ve demonstrated with the WALL-E picture ?

    Hi,

    First of all this article helped me a lot, being totally layman to these technical terms of photography, you simply written article helped me to understand a lot about aperture.

    I have a doubt, when you say low aperture setting say f/1.2 allows more light to come inside the camera on the other hand it focus more at object on the foreground and blur the background. When it allows more light inside then how does it blur the foreground object, ultimately it allows all light including background or foreground object.

    Please clarify :)

    thanks again

    • 107
      ) Fraidy

      Hi,

      “allows more light inside then how does it blur the foreground object?”…
      Light and the blurry object were not stand together.. you can also blurring the images in low light condition… the aperture condition can change the depth of field of the images, that depth of field can make your background sharp or blurry…
      f/1.2 can blurry your images nicely, but more than f/11 your background images will sharp.

      with f/1.2 you can blurring your images even in low light condition, but f/11 couldn’t do that. that’s why panorama or landscape images use f/10 or more to get the sharp background…

      hope you can understand…

    First I must thank you for your tutorials. They are truly helpful and your photos are truly amazing and beautiful. I have only recently been getting into the more technical side of photography and I was lucky enough to come by this wonderful website by chance.

    At present, I have just 1 question that has been puzzling me: I realize that a smaller aperture results in a greater depth of field. However, I have come across many landscape photos that display their EXIF metadata showing larger apertures of f4 & 5.6 and yet the whole photo is sharp and in focus from the foreground to the horizon.

    I would truly appreciate and be grateful if you could explain how this is possible, when I thought only apertures of f16 or so could achieve such DoF.

    Thankyou greatly

    Hello Mr. Mansurov,
    I have a simple Nikon coolpix s2600, and I’ve been wondering if it’s possible to even change the aperture settings on it as to render an image with a blurred background? All my images are sharp, however at times I wish to focus so as to remove background distractions. I believe the widest aperture it has is f/3.2, and from some internet research it seems thats wide enough to decrease the clarity of the background. Im not sure, though. Im quite clueless about cameras and am just wondering whether I can manipulate the settings on my camera, and if so, how. Thanks in advance

    I recently received a Nikon D3200 as a gift from my husband to start pursueing my photography passion. It only goes down to f/5.6 and to create the blurred background from everything that I have read I need a lense that goes to at least f/1.4. I just wanted to make sure this is correct before I purchase the lense. Thanks for the help:)

    First time writing and reading your blog. Thank you for so much information very helpful. I have a Nikon d5100. My 55-200mm lens says: 1:4-5.6G. Does this mean my highest f-stop is only 4-5.6? Very disappointed if so. I just got my camera a few months ago and the lens at Christmas. Do i need to buy ANOTHER lens in order to get the lens foreground crisp and background blurred? I’m a newly professed professional photographer picking up new tips here and there.
    Thank you so much.

    I am new to the DSLR world just purchased a Cannon Rebel T3. I took some pictures a few days ago out side making changes to the apature from f4-f22 trying to get used to the different settings. Today I went to take some more pictures again outside and all of the pictures are coming out white. I dont know what I did to cause this. If I put the settings an auto it does not do this. I have the ISO set at 100 as I was outside on a sunny day. WB was set to AWB. What am I doing wrong.

    Hi Nasim,

    I just came across your article regarding the basics terms used in photography and these are very helpful to me, as I am a novice in the field of photography. Moreover, I bought myself a Canon 600D with 18-55 Is lens recently and trying my hands in taking some nighttime photography (esp. low-light condition), but the pictures taken in low light are not as not clear as I have desired with enhanced ISO value and faster shutter speed with aperture fully open preferably in AV mode, TV mode (for moving vehicle, etc.), and manual mode…..I used all these modes while taking the pics but something is going wrong and i dont know where it is. Could you help me solving these issues and explain me the protocol at length for low-light photography with 18-55 mm IS lens…..Thanks and would be expecting a good input on this…Take care.

    hi. i enjoyed reding this and understand a little more about apeture. i just wanted to ask you a little more.
    im planning on going to iceland in december, and im hoping to be lucky enough to get a glimpse of the northern lights. everywhere i have read tells me i need an apeture of f1.4 or f2.8. i already own a fujifilm camera and its apeture is f3.1-5.6. when i eventually track down a lens to fit my camera, how would i go about setting the apeture to the right lenght. is it a case of zooming in and out or will i have to go through a menu settings.

    I have a Nikon D40 with 18-55mm lens. I’ve been trying to achieve these image results but haven’t reached there yet.

    And could you also tell me that if i try this on Manual Mode then what should the aperture and shutter be?

    Hi, I’m wondering if you could help, I am new to photography but will soon be purchasing the Nikon D600. I will be using it mainly for portrait photography and I hoping you could recommend a few lenses, possibly a cheap one, a medioka priced one and an expensive one? I was thinking the 85mm f/1.8 or the 85mm f/1.4 but wondering why the it seems the f/1.8 is more expensive when sure the f/1.4 is the better lens for background blur? Also the Nikon AF DC Nikkor 135mm f/2D but would appreciate any advice, I guess there would be the odd occasion where I might like to do just head and shoulders but as I will mainly be doing children and familys it will be mainly sit down or stand up poses or any pose with half body or full body in the photo so I’d assume anything 85mm or above lense wise would be best?

    Hi Naseem, Thank you for the excellent tips you have shared. It is wealth for us trying to learn on our own.

    I am currently using a point and shoot Cannon SX30IS. I am trying to experiment with the aperture mode. I used the Av mode and started playing with the lower “f” number , the max it makes me go below is 2.7, but i dont get the depth i want.

    Am i trying to do much with my simple point and shoot or am approaching it in a wrong way. Will the light factor during the time i was experimenting it affect how much low I can go ( since it was cloudy and quite dark outside)

I want to buy a new lens, I currently have the 18-55mm .I have children who play sports and would like to take pictures from far and get a clear phone of their funny face expressions. LOL. I am also looking for something to use an everyday basis but also looking for good sharpness. I was comparing and debating in between the 35mm and 50mm. Which one would you recommend, also is there any other one you like and recommend for beginner?
    Thank You,

I have a Nikon D40 with both Nikkor lenses 18-55mm and 55-200mm and when i try to take a picture on A mode, it takes a long time to process it and it comes out blurry. Do I have to have the camera on a tripod when i am taking the picutre on A mode? or is there something else that i have to do or put the camera on different features? I have always taken pictures on automatic mode and now, I am trying to learn the features of the camera.

    Dear Nasim,

    I had a wonderful time reading above article, it is indeed helpful and makes it very motivated in improving photo skills especially for beginners. I myself very new in photo-shooting field and honestly, I have learned so much from what you have elicited using simple and easy to understand language.

    Since you are professional photo-shooting guru, I would like to ask you a question if that’s not a problem. I appreciate your time and effort. My question is, I bought a Nikon Camera to take product photos as I am about to start an online business. I came across few articles in regards to different lenses used for various purpose such as for weddings and so forth. I was wondering if there is any lens exist for taking product photos that you know and can recommend me?

    ) Casey

    My question is for anyone who can answer. I consider myself intermediate. I know alot and feel like I am beyond the basics. My question is when I am shooting indoors on my canon t3i in low to moderate light I have the ISO at 3200 shutter 1/60 and I am shooting with a canon 17-55 2.8 with the aperture wide open at 2.8. Now the exposure is spot on and my center focus point is crisp sharp but the rest of the image is not clear, not really blurry or motion just doesn’t look as clear as the center. The subject for these pictures is the entire room for a real estate shot, so I want everything in sharp focus, I know to get the most light I need the biggest aperture, but to get better all photo focus am I going to have to lower it to 4.0 or smaller? Then I guess I’ll no longer be able to hand hold it and will just have to bite the bullet on pull out my tripod? Any advice greatly appreciated.

  100. I found the post very informative. Here’s my take on aperture: http://blog.pedromendes.com/aperture/

  101. Hi ,

    My first two weeks are here ;

    I used the sport mode for anything <50yrds, and a cheat for extra zoom on far shots from this site ;
    http://johnmorganphotography.blogspot.co.uk/2012/07/users-guide-to-lumix-g3.html
    I am fairly happy with most results, and very happy with a couple. I have defo got the bug now.
    I believe that I need to work on improving the focus, and reduce the white.
    Any tips and tricks for a beginner in nailing action shots would be greatly appreciated.
    Happy snapping

    thanks a lot

    • Hello Nagi,

      for macro photography I’d say a 100mm lens wound be good. For portrait you can get a 50mm 1.8 very cheaply, and that should get you started. 50mm is considered a ‘normal’ lense, tha one that photographs like the eye sees.

    Hello Nasir, I notice you have not responded to most post yet and wondering if this will be attended to. First let me thank you for this articles. They are really very good. I am not a beginner though but I dropped out for a while! I am trying to get back full time. I am into events and stuff ( weddings etc). I also do studio fotography too. Now my question, most times I have to use external flash as one can’t rely on internal flash of the camera so am wondering what settings will be appropriate for outdoor shoots when its sunny and when it isn’t. Also, general advise on taking excellent shots will be appreciate. I have Nikon D90 , D60 and canon 600D. Looking forward to hearing from u. BTW my flash is a canon430 EX and works fine wt all cameras

    • Hello Olumide,

      Do you mean using flash outdoors when it’s sunny? The main thing is using a flash strong enough to overpower the sun. A simple speedlight may not be able to do it. Also, flash or no flash, keep your subject out of direct sunlight, especially in the midday sun. Get them in the shade so the light isn’t so harsh. If you’d like, take a look at my blog, where I share photography tips (http://blog.pedromendes.com). All the best!

      • 158
        ) Olumide

        Well, yes. Are u saying the 430 EX isny strong enough ? There is a way flash light makes the picture extra sharp. And talking about sunglight, does the subject face the sun or otherwise ? I notice when they back the sunlight the picture becomes dull but when the face the sunlight and I back it it becomes clearer but they all have a squint in their faces !

        • It will depend on how strong the sunlight is. You will have to experiment. As you’ve said, if the subject faces the sun they will probably squint, and that’s not a good look :) If the sun is to their back, you may have flare (direct sun entering the lens). Flare can be a nice creative effect if you want it. Maybe the easier option is for the sun to be at their side. But you can try having the sun to their back, using fill flash if you need it, and using a lens hood to prevent flare.

    Hello Nasim,
    I have a Canon Eos 1100.
    I understand F-stops and how they work with shutter speed for exposure, however I have bought an OEM 650mm-1300mm zoom with a T2 Canon adaptor. The lens is fixed aperture F8-F16, depending on degree of zoom.
    When I switch to Aperture Priority, the F-stop reading on the screen is 1.6, and I cannot change it. I would like to make use of the TTL metering to automatically set the shutter speed (I have been using manual with the correct F-stop and then taking several shots with a variety of shutter speeds, hoping that one of them is right. The results are fine, but it wastes a lot of time, and I’m using the lens for wildlife, so the framing often changes whilst I am doing this)
    Do you have any suggestions on how I can get auto shutter speed setting?
    Many thanks

    Hello!
    If I had a camera 1 with f/2 and max ISO of 6400 in comparison to camera 2 with f/2.8 and max ISO of 12800, which will be the camera that will perform better in low light scenarios without flash? Would they cancel out as I am slightly confused..

    I took 2 photos with same aperture, shutter speed and ISO in aperture mode using my nikon d3200. But in one photo the background was blurred, but on the other, foreground was blurred. what could be reason?
    f3.5, 1/4000 sec, focal length: 18mm.

    The only difference I can see is ISO 283 in the image where background was blurred, and ISO 200 in the image where the foreground was blurred.

    I want you to know that in all I have read to learn about Aperture, I have never understood better, then by the way you teach it. Please keep up the wonderful work! I belong to a photography forum with many pros, and I am a beginner. I don’t want to just snap, shots anymore, I want to be more then a mediocre photographer, I love beautiful photos, and want to learn.

    Thank you soooooo much, and I will continue to read your tutorials because they are so excellent for me!!

    Dear Nasim,
    thanx for your explaination. Now I understand what is apperture. Before it was not clear to me, I had read many articles, but still could not understand the meaning of apparture mode.

    I have one small request: I have purchased a new Nikon D5300 DSLR with 18-55 standard lens. After your explaination I understood that I need another lense with maximum f-number. Could you please advise what type of lense is the most suitable and affordable for my camera if I want to use it friquently with zoom in/out and maximum f-number.

    And it would be appriciated if you had explained alsi what is shutter speed and where it can be used as well.
    Kind regards.

    I must correct myself i nmy previous message…
    I need lense with maximum aparture, not maximum f-number.

    I am a beginner, so, please forgive me for my non-professonalism. :)
