One of the challenges of nighttime photography — particularly Milky Way and star photography — is to get enough depth of field. If you’re focused at the horizon, and you’re using the widest possible aperture on your lens, how could your foreground possibly be sharp? Yet, if you look at galleries online, you’ll see countless photographers capturing perfectly sharp photos of a landscape underneath the night sky. What techniques are they using? In this quick guide, I’ll lay out a few useful tips for capturing sharp landscape photos at night.
When taking pictures, one of the biggest frustrations one can experience is camera shake, which often happens as a result of the way the camera is held at lower shutter speeds. Properly hand-holding a camera can drastically reduce human-induced camera shake and result in many more sharp images and keepers. In this article, we will discuss a few different ways to hold a camera, which will hopefully reduce and potentially even eliminate unwanted blurry images when you are shooting in the field.
Depth of field (DoF) is one of the most important concepts in photography. Understanding what DoF is, and knowing what factors affect it, are things all photographers should master. Many photographers know that you can control DoF by adjusting aperture. But did you know that DoF is influenced by other factors too? In this article, I want to explain in simple terms what depth of field is and talk about the ways you can control it.
There are many combinations of aperture, shutter speed, and ISO that will correctly expose an image. With all those combinations, which one is the right one? If you leave your camera in full program mode, your camera will pick a combination for you. However, letting your camera have complete control is not why you bought an expensive DSLR or mirrorless camera! Learning how to adjust the settings and modes on your camera before you click the shutter will give you the upper hand. You will end up capturing images creatively, rather than by chance. Read on to find out how aperture, shutter speed, and ISO affect the look and feel of a photograph and how to choose the best camera settings to take creative control of your images.
Photographers have a dilemma. If you want your photographs to have the largest possible depth of field – from the foreground to infinity – a small aperture is absolutely necessary. At the same time, though, a small aperture causes your photograph to lose sharpness from diffraction. So, where’s the sweet spot? In this article, I will cover how to choose the sharpest possible aperture for such a photograph, including mathematically accurate charts (free for printing) that are easy to use in the field.
When photographers talk about lens diffraction, they are referring to the fact that a photograph grows progressively less sharp at small aperture values – f/16, f/22, and so on. As you stop down your lens to such small apertures, the finest detail in your photographs will begin to blur. With good reason, this effect can worry beginning photographers. However, if you understand how diffraction impacts your photographs, you can make educated decisions and take the sharpest possible photographs in the field. In this article, we will explore the topic of lens diffraction in detail and talk about different techniques you can utilize to avoid it.
Aperture is a confusing topic for beginners in photography – it controls so many variables in your images, from exposure to depth of field, which can make it quite difficult to grasp initially. To make matters worse, the F-numbers of aperture are backwards from what you may expect! A small aperture is a large F-number, and a large aperture is a small F-number. I certainly was confused by aperture when I first started taking pictures, and it took me quite a while to really understand how it works. Nasim already covered aperture in-depth for beginners, but I wanted to pass along a quick diagram that I made – hopefully something that you will find useful. This chart covers the most important effects of aperture in photography, as well as common terms that photographers use to describe their settings.
There is so much duality in photography. On one hand, it’s the light and the subject, it’s the story we tell and the story the viewer sees, it’s a feeling, an emotion, a state, a symbol, a metaphor. Sounds poetic, doesn’t it? On the other hand, it’s pure science, every single bit of it – from the said light traveling through a complex lens design, all the way to the scene being imprinted whether on a piece of light-sensitive film or, temporarily, on a digital sensor. And that scientific part of photography brings all sorts of terms with it, terms that may not be necessary for the creative process, but as far as skillful execution goes, you can’t do without understanding them for very long. A painter needs to know his brushes at some point, right?
And so we are back to covering basics, something you surely must have noticed. In this article, I will talk about yet another, confusing-at-first-encounter term used in photography, more specifically – exposure stops. I will try to explain what they are and how stops of different exposure triangle parameters – shutter speed, aperture and ISO sensitivity – correlate, as well as give you examples of what are considered to be regular stop values of each parameter, and what are full, half and third-stops.
The subject of sensor crop factors and equivalence has become rather controversial between photographers, sparking heated debates on photography sites and forums. So much has been posted on this topic, that it almost feels redundant to write about it again. Sadly, with all the great and not-so-great information out there on equivalence, many photographers are only left more puzzled and confused. Thanks to so many different formats available today, including 1″/CX, Micro Four Thirds, APS-C, 35mm/Full Frame, Medium Format (in different sizes), photographers are comparing these systems by calculating their equivalent focal lengths, apertures, depth of field, camera to subject distances, hyperfocal distances and other technical jargon, to prove the inferiority or the superiority of one system over another. In this article, I want to bring up some of these points and express my subjective opinion on the matter. Recognizing that this topic is one of the never-ending debates with strong arguments from all sides, I do realize that some of our readers may disagree with my statements and arguments. So if you do disagree with what I say, please provide your opinion in a civilized manner in the comments section below.
Today is another sad day, because Apple announced that it will no longer continue development of its Aperture software, which many photographers still rely on for their day to day photo management and editing. Too bad, because this basically gives Adobe monopoly with its Lightroom software. Yes, there are some other tools on the market such as ACDSee Pro, Phase One Capture One Pro and a few others, but none of them come to close to what Lightroom offers in terms of features, photo catalog management and up to date RAW file support. Aperture has not seen any major updates since October of 2013 and has not received support for the latest cameras that were announced this year, with only a small minor updates. Many of us saw this coming, but none were expecting the death of Aperture so soon.
