Photographic Myths and Platitudes: The Best Camera! (part 1)

August 6, 2015 G Dan Mitchell 8 Comments

Three manufacturers companies now produce widely available full-frame digital cameras with features that are attractive to folks who photograph landscape subjects, among other things. Two of them recently released new models that are getting a lot of attention, and plenty of photographers are interested in their relative merits and perhaps in choosing among them.

The three I’m thinking of are:

Here is a statement that a thoughtful, experienced, knowledgable photographer who has looked at the options carefully and selected one of them might make:

I chose this camera because it exemplifies the continuing evolution and improvement of digital cameras. It introduces useful and powerful improvements that offer the potential of a range of image quality improvements. The camera has the ability to produce photographs with outstanding image quality in a wide range of conditions and circumstances, and photographers who use it are going to be very pleased with what it can do. It has its pluses and minuses, and other cameras may be a bit stronger or weaker in various areas, but on balance it is a first-class and powerful tool that works extremely well for the most demanding photographers. I recommend that other photographers take a look at it!

The question: To which of the three (and a half?) above-listed cameras does this statement apply?

If you have paid a lot of attention to the passionate and hyperbole-filled discussions and “tests” that inevitably accompany the release of new cameras, you have read proclamations that any one of those is “the best” or even that it will transform your photography. And it is possible that “the answer” is already obvious to you, and you are certain that one surpasses the others in obvious ways. You might even have come to the conclusion that a photographer choosing one of the other options is making a mistake, is probably unaware of the significance of the error, and that his/her photographs are likely to suffer as a consequence of this flawed decision.

With all of that in mind, the answer is… Continue reading Photographic Myths and Platitudes: The Best Camera! (part 1) →

Doorway, Stairs

August 6, 2015 G Dan Mitchell 1 Comment

A doorway opens to a lighted passageway and ascending stairs.

A small group of photographers was exploring portions of nighttime San Francisco on a recent evening, making their way from North Beach through Chinatown and towards the Union Square area. As we photographed and walked the light transitioned from evening (with some sun visible in places) to dusk (as lights came on) and then to darkness — at least as dark as it gets in this City on a Friday night. Our path took us to some areas that are not as frequently visited by tourists, but it also took us straight down a section of Grant Avenue.

Grant Avenue is what comes to mind for many people when they think of San Francisco’s Chinatown. Grant is the touristy “main drag” of the area, lined with a range of shops and business and restaurants, many of which appeal to tourists. At night much of this area shuts down, though restaurants remain open — but even as things close the light remains interesting. So we walked down Grant, stopping to photograph various things along the way. At one point we passed this somewhat mysterious doorway. Most such entrances are closed up tight, usually with a locked gate in front, but this one was open and light from the stairway inside flooded out onto the sidewalk. The walls around the door are painted in many colors, and ambient lighting adds another layer of color. My first thought was to make this a color photograph, but as I looked at it in post that seemed just a bit too obvious so I went with this monochrome rendition instead.

Glaciated Ridge and Trees, Morning

Trees growing on rocky, glaciated granite terrain in morning light

Among folks who know me a bit, it is not a surprise to hear that this is my favorite kind of Sierra light — early morning light coming across hazy ridges and granite and striking sparse trees from behind, creating a glow among their branches. I can’t explain why it draws me, but it does, and I think it always has. Perhaps I saw something, now forgotten, during one of my first visits to the Sierra, or possibly I saw a photograph (possibly in one of my father’s books) many years ago and it made an impression.

This scene is obviously not a Yosemite icon (though one is nearby), but the nature of the view is iconic Yosemite for me. A handful of things seem characteristic of the Yosemite high country, and one of them is the sight of granite domes, usually with broken rock, and widely separated trees somehow eking out a livelihood on what appears to be bare rock. Undoubtedly, more square miles of the park are covered by forest, but we can find forest almost anywhere — these trees thriving on bare granite are more rare and more a special characteristic of this place.

Photographic Myths and Platitudes — That Sensor Noise is Awful!

August 4, 2015 G Dan Mitchell 4 Comments

Let’s say you are looking for a new camera. You want to make a smart decision, especially since you are sinking your hard-earned money into the purchase. You sure don’t want to make a mistake and end up with deficient gear. So you do the smart thing — you do some research. You look around on the web, find some articles, and you discover that there is a lot of contradictory information. Some tell you that Product X is wonderful, while others are adamant that Product X is pathetic and that Product Y is far superior. The Product X fans point out that Product Y is deficient in other critical ways by comparison to Product X.

You have some unanswered questions.

I keep hearing that Camera X has terrible noise compared to Camera Y. In fact, I found some photographs that demonstrate how bad this noise is. Why in the world would anyone get Camera X?!

Both sides provide “evidence.” Photographers love evidence, especially evidence of a failure to achieve divine technological perfection, and double-especially when the failure is demonstrated in a brand they don’t own. They get a little testy though, when the “evidence” makes their product look weak! (For a fun detour, look up the term confirmation bias on the web. Also, this is an important time for a reminder that photography is about photographs, not about cameras.)

I want to construct a little story for you based on “evidence.” We’ll start with evidence that makes a particular product (one that I rely on) look particularly bad. But before we start, you need to promise to read the whole thing. I’ll try to make it worthwhile.

OK, I promise to read it all, and with an open mind.

Good. Here we go.

Lots of people are concerned with the related issues of dynamic range (the camera’s ability to record image data from both light and dark sources in a single photograph) and noise (non-image artifacts that are, in a rough sense, sort of like “grain” on film).

I’ll begin with an example of noise in a photograph I made using the the new and very expensive Canon EOS 5Ds R, a 50.6MP full frame DSLR that Canon released recently.

045DsRPushedAbsurdly100PercentCrop — Example #1

Man, that is awful! That 5Ds R obviously produces terrible noise. It is so bad that the photograph is unusable, at least for anything other than an article demonstrating how bad it is! And the color is pathetically bad, too!

Yes. That image looks absolutely horrible!

Astute, critical thinkers are already wondering what went wrong here. Let me explain. Continue reading Photographic Myths and Platitudes — That Sensor Noise is Awful! →
