The latest Nikon DSLRs like D810 (see our detailed review) and D4S came with the a new “Group-area Autofocus” mode. When compared to the regular Single-Point AF Mode, Group-area AF activates five focus points to track subjects. This focus mode is great for initial focus acquisition and tracking of subjects when compared to a Single-Point or Dynamic AF, especially when dealing with smaller birds that fly erratically and can be really hard to focus on and track. In such situations, the Group-area AF mode might give better results than Dynamic AF, showing better accuracy and consistency from shot to shot.
It has taken a little longer than I wanted, but I finally got around to writing this second article on photographing wildlife. The writer in me is still struggling to get out, wants to keep hiding and do more interesting stuff like taking photographs rather than write about it. Let’s get started and see where it leads. If you would like to read the previous part, please see this link.
Incredibly, the first domes date back to people living in the Mediterranean region 4,000 years BC. Since then, artists have created a fascinating variety of them all over the world. Still today, they are an essential part of modern architecture, as shown for example by Calatrava’s spectacular glass dome of the library of the Institute of Law in Zurich, Switzerland.
When light rays coming from a bright source(s) of light (such as the sun or artificial light) directly reach the front element of a camera lens, they can reflect and bounce off different lens elements, diaphragm and even off the sensor, potentially degrading image quality and creating unwanted objects in images. Better known as lens “flare”, the effect can impact images in a number of ways: it can drastically reduce image contrast by introducing haze in different colors, it can add circular or semi-circular halos or “ghosts” and even odd-shaped semi-transparent objects of various color intensities. Flare is not always undesirable in photography though – sometimes in is used creatively to add artistic elements to images. In fact, lens flare is often deliberately added to movies and computer games to add a sense of realism and boost the visual experience of the viewer.
Vignetting, also known as “light fall-off” (sometimes spelled “light falloff”) is common in optics and photography, which in simple terms means darkening of image corners when compared to the center. Vignetting is either caused by optics, or is purposefully added in post-processing in order to draw the viewer’s eye away from the distractions in the corner, towards the center of the image. Depending on the type and cause of vignetting, it can be gradual or abrupt. There are a number of causes of optical vignetting – it can naturally occur in all lenses, or can be caused or increased/intensified due to use of external tools such as filters, filter holders and lens hoods. In this article, I will talk about each type of vignetting and also discuss ways to reduce or increase the amount of vignetting in photographs using post-processing software like Lightroom and Photoshop.
This year’s vacation choice was a simple one. Based on last year’s trip to the Canmore/Banff area, we realized there was much more to see of this beautiful region than time allowed. Many of the Photography Life readers were kind enough to suggest possible itineraries for our next trip. In particular, Cindy (a.k.a. “Alberta Girl”) gave us a detailed listing rivaling the length of my original article! Her recommendations served as the foundation for this year’s itinerary. If you are seeking to combine your love of photography with hiking, wildlife viewing, and breathtaking scenery, I would strongly urge you to consider the area around Banff National Park. I guarantee you will not be disappointed.
In photography, there are two types of distortions: optical and perspective. Both result in some kind of deformation of images – some lightly and others very noticeably. While optical distortion is caused by the optical design of lenses (and is therefore often called “lens distortion”), perspective distortion is caused by the position of the camera relative to the subject or by the position of the subject within the image frame. And it is certainly important to distinguish between these types of distortions and identify them, since you will see them all quite a bit in photography. The goal of this article is to explain each distortion type in detail, with illustrations and image samples.
Summertime for wedding photographers in the northern hemisphere can be quite hectic! Since the beginning of May I have been shooting 3-5 portraits sessions and 1-2 weddings per week – that means before I have little time to process, edit, and complete a session/wedding before I am already onto the next one. It goes without saying that good time management is crucial for not falling behind. In this article, I will share a few time savings tips for busy photographers like me.
Many photographers prefer to have second shooters to help them out during events, especially big weddings. Hiring or becoming a second photographer to work along with you on a job might be very complicated, tricky and sometimes downright nightmarish. You hire a photographer to come and help you out during one of the biggest weddings of your season, and the photographer shows up late, completely unprepared, with empty batteries, no flash and a completely different camera system. If you wish to avoid such situations, read this post up and make yourself thoroughly prepared. It sure is a hard job to let someone else represent your business. But when you are ready, you can make the experience both pleasant and even memorable for all parties involved.
I have a very unique Nikon D7100 – it is likely the first unit converted for infrared use – in the world. My D7100 is also likely the first to undergo two infrared conversions (more on this in a bit). I was fortunate to receive my D7100 from B&H as part of the first wave of product shipments. Apart from a night of putting the DSLR through its paces to ensure that there were no focusing problems or other issues, I didn’t have the D7100 for very long. For the many reasons Nasim outlined in his detailed D7100 review, and being very familiar with its predecessor, the D7000, I liked what I saw of this DSLR’s capabilities.
