What is a Decentered Lens?

A decentered lens contains one or more optical lens elements that are either moved or tilted from the principal axis of the lens. Such shifting or tilting of lens elements can potentially lead to blurring / softness of parts of the image due to divergence of light rays. While very slight decentering of optical elements can be observed in many lenses, especially on superzooms, severe decentering and tilting can render the whole image blurry, with the lens unable to achieve…

The Nikon D810 is an advanced camera and comes with many different menus and settings. In this article, I want to provide some information on what I personally use and shortly explain what some of the important settings do. Please do keep in mind that while these work for me, it does not mean that…

Nikon Group-Area AF Mode

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,…

We are continuing our series of recommended settings for cameras and this time we have the Sony A6000, an advanced interchangeable lens camera designed for enthusiasts and professionals. In this article, I want to provide some information on what settings I use and shortly explain what some of the important settings do. Please do keep in mind that while these work for me, it does not mean that everyone else should be shooting with exactly the same settings. The Sony…

Recommended Canon 6D Settings

After we’ve published our series on recommended settings for Nikon D600 / D610 and D800 / D800E DSLRs, we received a lot of requests from our readers to provide similar information for Canon and Sony cameras. While using someone else’s camera settings is probably not the best way to achieve the best results in every situation, we understand that many different menu options can be rather overwhelming for those who are just starting out. Therefore, the below information is provided…

How to Focus Stack Images

For most people who just want to have some fun with their photography and have another ‘trick up their sleeve’ focus stacking can be an interesting technique to explore. To put this article in proper context, I’ve never used focus stacking for any of my client work, and I don’t profess to be an expert at the technique…but I have experimented with it. The following image is a quick focus stacking example I put together for this article. It was…

How to Photograph a Rainbow

Rainbows are rare in nature, because a number of events have to happen at the same time. First, there has to be moisture in the sky, so a rainy day or a quick rainstorm is the first pre-requisite. Second, the sun must be positioned on the horizon at a low angle, around 42 degrees relative to the viewer. Third, the part of the sky where the sun is must be clear from clouds and obstructions, while the part of the…

How to Photograph Clouds

Nature often rewards us with incredible opportunities for photographing sunrises, sunsets and sun rays piercing through the clouds, creating stunning views. As a landscape photographer, I tend to wait for partly cloudy and stormy days, because clouds make photographs appear much more dramatic and vivid. Without clouds, sunrises and sunsets often look boring, forcing us to cut out the sky and focus on foreground elements instead. In contrast, if you get to witness a sunrise or a sunset with puffy,…

Not All Lens Filters Are The Same

The subject of using or not using protective lenses can invoke heated debates among photographers, with both sides often fiercely defending their choices. I am not going to debate whether it is right or wrong to use protective filters – that’s certainly a personal choice. I have been using them for a number of years now to protect my higher-end lenses and make it easier to clean lenses with recessed front elements (such as on Nikon 50mm f/1.4G / f/1.8G).…

Case Study: Shooting NYC Skyline

A good friend of mine, Yechiel Orgel, who is a professional commercial photographer specializing in product photography out of NYC, contacted me last week and asked for some advice on shooting the New York City Skyline from a rooftop of a luxury condo building in Brooklyn. The aim of the shoot was to show the NYC skyline that can be seen from the roof of this building. The building is located in downtown Brooklyn, roughly 3 avenue blocks from the…

Recommended Nikon D800 / D800E Settings

After I published the article on the recommended settings for the Nikon D600 / D610, I received plenty of requests from our readers that asked me to write a similar article for the Nikon D800 and D800E cameras. Since I own and use both frequently, I decided to expand the series to other cameras (and I do have plans to publish similar articles for Canon DSLRs as well). In this article, I want to provide some information on what settings…

Recommended Nikon D600 / D610 Settings

One of our readers recently asked me to provide my settings from the Nikon D600 / D610 cameras that I use for my photography needs. While at first I thought that it was an odd request, it got me into thinking that many photographers probably get lost trying to dig through the many menu options. Since I have been shooting with Nikon for a number of years now, those settings are very easy for me to understand and I apply…

How to Deal with Light Frequency Issue

When photographing in artificial light, one has to always watch out for the potential light frequency issue. Due to the different intensities and wavelengths of light emitted by fluorescent and other sources of man-made light, there might be severe variations in exposure when photographing at fast shutter speeds. This is a similar “flickering” issue that you see when photographing or video-recording a TV screen – different light frequencies cause the flicker that is recorded by the camera. This can happen…

What is Arca-Swiss Quick Release System?

Many of our readers frequently ask us questions about tripod heads and accessories to support heavy camera and lens combinations. Those that are especially new to super telephoto lenses quickly discover that tripod feet supplied by all manufacturers on modern lenses are simply not suitable to be mounted on regular tripod heads. Unfortunately, whether it is Nikon, Canon, Sony or a third party lens manufacturer like Sigma, they all supply non-standard tripod feet with their lenses. For new lens owners…

The Riddle of Intermediate ISO Settings

I guess today is a “blow your mind” Friday, because we have a guest post here by Iliah Borg, the person behind the RawDigger software that is used to analyze RAW images. I had a chance to engage in a conversation with Iliah when discussing the noise performance of the Nikon Df, where he not only proved me wrong on my assumption that the Df had exactly the same sensor as the D4 (turns out that they are similar, but…

A Fifty for Creativity

Even just a few hours ago, I was once again asked by a reader what lenses do I use most for my wedding photography. The answer is and always has been the same for my wedding, family or general photography needs – a classic fifty. I am sure hardly anyone will find this at all surprising, because fast 50mm fixed focal length lenses have become a legend of sorts. Ask any photographer and he will tell you – that is…

Do Filters Affect the Resolution of Lenses?

Just like the old “film vs digital” or the “Nikon vs Canon” debates, lens filters often create endless discussions on the Internet. Some people argue that one should never use protective filters, since it is another piece of glass in front of the lens that reduces resolution and emphasizes other optical problems such as ghosting / flare, while others argue that filters make it easier to protect the front element of the lens and make it easier to clean that…

What is an Extension Tube?

Our readers frequently ask us about extension tubes for macro photography. Since I am not much into macro myself, I have not explored this area of photography enough to qualify to write about it. While I have done some macro photography for product shots and ring shots in weddings with my Nikon 105mm f/2.8G VR lens (a very sharp lens that I absolutely love), I have not explored its full capabilities and I have not tried to use extension tubes…

What is Composition in Photography?

With the first article in our new Mastering Composition series, it is only fitting that we start off by discussing the very definition of our main topic. In this article for beginner photographers, I will outline the general meaning of the term “composition” in art. I will also briefly discuss the goal of composition, define what a good composition is and why it is such an important part of any work of art. At the end of the article I…
