Is Sony’s Color Science Really That Bad?

One of the biggest complaints I hear quite regularly about Sony mirrorless cameras is that their color science is horrible. Many photographers don’t seem to like how Sony interprets colors from any given scene. This it seems, to be especially true for portrait photographers. In stark contrast, color science is one of the major positive points for Canon cameras.

Nikon Z7 Teardown: Inside Nikon’s 1st Full-Frame Mirrorless Camera

Our brand new Nikon Z7 full frame mirrorless camera arrived at the office this week, and we immediately got down to business. Four years ago, Sony fired the first shot of this battle with the A7 and continued to release one iteration after another, each improving on the last, and did so completely unanswered by the competition until August 23rd of this year when Nikon announced the Z7 and the Z6.

It’s the Exposure Quadrangle, Not Triangle

The Exposure Triangle; you’ve heard of it, I’m sure. It’s fabled in story and song and celebrated by photo instructors everywhere. We can even buy t-shirts commemorating the concept! There have been countless articles written about the “exposure triangle” (try a Web search and see for yourself), all with the intent of helping newcomers to photography figure out how exposure works in their cameras.

Continuous Lighting vs. Strobes: The Pros and Cons of Each

It’s photographer Jay P. Morgan here. Here's a new 11-minute video in which I compare the pros and cons of strobes vs. continuous light and conduct some indoor and outdoor lighting tests between the two for you to decide which one to use when you are shooting.

iPhone XS: A Look at the New Camera (and Debunking the ‘Beauty Filter’)

My name is Sebastiaan de With, and I’m the designer of the iPhone camera app Halide. I recently detailed the camera hardware changes of the iPhone XS vs. the iPhone X, and I wondered why Apple’s keynote focused on changes in camera software rather than the new hardware. After testing the iPhone XS cameras for the last week, I get it.

iPhone XS vs. iPhone X : A Look at the Camera Hardware Changes

My name is Sebastiaan de With, and I'm the co-founder and designer of the iPhone camera app Halide. Some reviewers with advance access to the iPhone XS have been kind enough to share technical readouts of the new phones with our team, detailing several camera hardware specs. After some analysis, we can now give you an overview of what’s new in the iPhone XS camera hardware and its technical capabilities beyond what Apple stated at their keynote.

8, 12, 14 vs 16-Bit Depth: What Do You Really Need?!

“Bit depth” is one of those terms we’ve all run into, but very few photographers truly understand. Photoshop offers 8, 16, and 32-bit file formats. Sometimes we see files referred to as being 24 of 48-bit. And our cameras often offer 12 vs 14-bit files (though you might get 16-bit with a medium format camera). What does it all mean, and what really matters?

PSA: It’s ‘Bokeh’ not ‘Bokuh’

There are many sounds that native American English speakers have trouble reproducing. The French “r” (aka the “voiceless uvular fricative”), the rolled double “rr” in Spanish, tonal sounds in various Chinese languages like Mandarin and Cantonese.

How Still Life Came to the World of Photography

A while back, I had another roundtable discussion at the Film Photographers Association. This time the subject was Still Life Photography. It is a genre we all take for granted and include in it a great variety of photographs. I would like to explore the origins of still life in painting, how it came to photography, and eventually expanded in coverage and scope.

When and How to Use a Polarizing Filter

Reflections are often unwanted, and glare will wash out an image. Polarizing filters counter the reflective measures and will deepen blues and add contrast to skies, reduce or remove reflections from water and windows, and increase contrast and saturation.

Histogram or Artistic Expression: What Matters Most?

How literally should you interpret a histogram? Where do the lines intersect between artistic expression and photographic technicalities? It’s important to first recognize that a histogram is nothing more than a mathematical representation.

Impostor Syndrome Might Be Where Your Self Doubt Comes From

I don’t deserve to be writing this because there are more capable people who can speak more eloquently than I can that can deliver this message to you. This is exact thought that went through my head as I was writing this blog post because I’m not the best writer.

Flange Distance and Mount Diameter Explained by a Lens Engineer

Nikon has understandably made a big deal about launching their new Z-mount alongside the announcement of their new mirrorless cameras, the Z6 and Z7. The Nikon F-mount was originally released 59 years ago and the company has made backward compatibility of the system a brand pillar.

How to Look After Your Eyes as a Photographer

Sight is very important to me. It’s one of my senses that I don’t think I could ever do without. A musician might fear going deaf, but I could live with that. I’d rather not have to but if it came down to losing my hearing or losing my vision, I’d take being deaf. That’s just me.

How Much Depth-of-Field Do You Get with Nikon’s 58mm f/0.95 Lens?

Along with the announcement of Nikon’s new mirrorless Z-system was the development announcement of a 58mm f/0.95 Noct lens. The Z-mount’s huge inner diameter of 55mm (the F-mount has a 44mm diameter) means more light collection capability, which enables ridiculously fast lens design. Nikon’s F-mount 58mm offering tops out at f/1.4.

Is the Sensor or the Lens to Blame for Poor Image Quality?

A few years ago, I was embarrassingly very vocal about how disappointed I was about some of the Nikon lenses. I've been using Nikon cameras and lenses for decades and although I was very pleased with the image quality and color rendition their cameras produced, I strongly considered jumping the Nikon ship in search of crisper, cleaner looking lenses.

This is How Canon Supports its Pros

As the camera wars are heating up over the new battleground that is mirrorless cameras, the heavyweights in the industry are taking turns tooting their own horns. Canon just released this 2.5-minute video on the benefits of Canon Professional Services (CPS).

How Camera Film Gets Processed in a Lab

I was recently fortunate enough to get an inside and ‘behind-the-scenes’ look into how film processing works at Richard Photo Lab in Valencia, CA. As the step by step process is very complex, if you’ve ever wondered what the stages of film developing are and look like, come and take this video tour with us!

How to Find the ‘Sweet Spot’ of Your Lens for Sharper Photos

When it comes to purchasing a new lens there are two questions that immediately come to mind for me, how much is it and how sharp is it? Now, I know there’s more to the lens buying process than overall sharpness, but as a landscape photographer, sharpness is king!

Behind the Curtains of a Best Buy Camera Shop

I was hesitant when I first found out that Best Buy had a camera shop in their stores. My experience in the past had been a disappointment, walking through their small camera section was underwhelming and most of the associates avoided that area. I didn’t think too much of it, as cameras were not generally accepted knowledge like it is with computers or TVs. Your average employee would have issues talking about ISO, shutter speed, aperture, and the practical application of these terms.

Portraits of the Konyak ‘Headhunter’ Tribe in India

When we think of tribes, the first thing that comes to our mind is, “what did those tribesmen and women believe in?” “What were their customs and beliefs?” That’s what I asked about the Konyak tribe that was nestled in Nagaland, India, in regard to the famous headhunters.

Slide vs Color Negative Film: How They Compare and When to Use Each

Film is on the resurgence as of late. Transparency film is another option from your regular negative film, but what is it exactly? When would you use transparency instead? How does it compare to C-41 or print film? And what is the dynamic range of transparency film? In this article, we'll answer those questions and more.

Why and How to Use a Star Tracker for Photos of the Night Sky

Astrophotography is generally a race against time to capture as much subtle starlight we can before the stars create trails in our images. The movement of the Earth puts a natural limit on how much sharp, subtle detail we can reveal. We have to use super fast, wide angle lenses and high ISO values to see all the awesome detail. Fortunately, a tool exists to circumvent this barrier to reveal more of the hidden magic we have in our night sky.

Yes, Nikon Designs Its Own Sensors

Sony has been receiving attention and praise in recent years for the quality of its sensors and the fact that it produces sensors for other heavyweight camera companies, including Nikon. But even though some of Nikon's CMOS sensors may be manufactured in Sony factories, Nikon actually spends a considerable amount of resources designing those high-end sensors.

Is Lens Compression Fact or Fiction?

Photography can be confusing. I get it. I am not the sharpest knife in the drawer. Because of this, at times it helps us to actually put some of these theories and myths to the test. One of these myths is the concept of compression and, with it, parallax.

How Canon DSLRs Communicate with Speedlites Using Light

Canon DSLRs can trigger Canon Speedlites using the pop-up flash. If you try triggering those same Speedlites with a different camera's flash, it doesn't work, which means that there's actual light-based communication going on between the DSLR and Speedlite. In this 9-minute video, Roger Nieh of Science'n'me explores the technology behind this communication.
