Concerning Megapixels

(This is another in a series of articles based on posts I shared elsewhere. This one is based on a reply to a post concerning how important it is to move to a newer, improved sensor with higher photo site density. The immediate question had to do with how often the improvements would be significant enough to be seen, and the writer had correctly pointed out that there can be advantages to higher “MP count” when making very large, high quality prints.)

It is useful to try for a realistic understanding of how and when a higher MP sensor may show its advantages. This post tries to not take a position on brands and models, but rather to lay out a comparison of some relevant technical stuff — from which we can all draw our own individual conclusions.

There is a point below which you would be hard pressed to tell the difference between prints made from 22MP and 36MP cameras and above which you might be able to.(1) For example, virtually everyone would agree that the difference is typically completely invisible in small web images, and virtually everyone would agree that it could be visible if you closely inspect a print that is six feet wide. Since we could debate just where the boundary is — and, frankly, it is somewhat subjective — you could pick any point on the print size scale that you want and the principles will be the same.

Some Comparisons

Just for fun, let me use completely arbitrarily use two print sizes and base the comparisons on the 22MP Canon 5D Mark III and the Sony/Canon 36MP sensor cameras. Continue reading Concerning Megapixels

A narrow, empty street curves past small shops in New York City’s Chinatown

First off, I’m obviously not a “real” New Yorker — I love the place, but I’m most certainly a visitor and a west coast guy at heart. However, that means that for me many things that might seem familiar and perhaps even ordinary to long time New Yorkers are still special and new. My first visit to New York’s Chinatown area was only a few years ago. We came into the city on Christmas Eve and pretty much the only restaurants open nearby (we were staying on Canal Street) were in Chinatown, so we plunged into the throngs that typically seem to crowd the sidewalks here, eventually wandered down some narrow streets, and arrived at a restaurant where we met up with friends and family members for a wonderful dinner.

This time we got there a bit later during our trip, on an evening when we were all perhaps becoming just a bit travel-tired and when we wanted a dinner that wasn’t quite so expensive as some others we had recently enjoyed. One or both of our sons suggested that we meet up at a place in Chinatown again, and since we arrived a bit early I took advantage of the situation and made a few photographs on this wonderful little street, with its beautiful curve, small shops, and wildly colorful store fronts and signs. Most of the time this street was busy with passing pedestrians, but I waited a bit and managed to make this photograph of the empty street in the evening light. The details of such photographs are often fun and intriguing — the picture on the hair salon sign at the left, the bicycle sitting on its rear wheel at the far right, the colorful flags on one store front, and more.

Print Review (Morning Musings for 8/19/14)

We are very fortunate to be part of a small group of photographers and friends who gather every six weeks or so in one of our homes for an informal print review. Each of the photographers is talented and expressive, and while our stylistic and subject preferences overlap, each has a unique style and photographic “voice.”

Print reviews, especially when the participants comprise a group of very talented and perceptive photographers who are also friends, are very, very useful. They tend to force me to switch out of the regular ongoing “flow” of making a lot of photographs, and towards a more directed task of choosing work worthy of showing and then making decent prints of the work. This switch is another element of the “discipline” component of photography. Even more important, I hear diverse responses to the work, which range from the purely emotional (very important) to technical observations (also important).

It is interesting to see the range of responses — sometimes they are pretty much what I expected based on my own relationship to the images, but at other times I’m surprised. I had two of those surprises last night, and each of them came in the case of sets of related prints that I shared. One was a small group of three street photographs from my recent visit to New York City, photographs of dense and busy spaces that feature intense and wild color palettes. I had originally preferred one of the images to the others, but was beginning to gravitate to a second one in the set that included many more people. To my surprise, the group responded most strongly to the third, and their reactions to it made me reconsider my own feelings about the images in several ways.

The second group of photographs included five high-key black and white photographs, all of which belong to minimalist thread in my work that is about luminous atmosphere, usually from fog, that is so brightly lit by sun that it almost hurts to look into the scene. In order to get prints to somehow suggest that quality, I push the luminosity levels up about as far as possible, and the resulting images are somewhat minimal and often contain large areas of gentle tonal gradation. Among the five I shared were four that I made in California’s Central Valley. One of these is truly minimal, with a nearly invisible and diffuse horizon dividing an extremely luminous foggy sky from its reflection in still water below, and the only clear details are a few scattered birds in the water. I had almost chosen to not include this print, thinking that it might just be too minimal for other viewers. Much to my surprise, and without any prodding from me, the group preferred this image over the others. Live and learn!

Finally, it is a wonderful and useful discipline to hear my work critiqued and mostly adopt a learner’s attitude about what I hear. It is in my nature to try to persuade others of my point of view, but that is usually (but not quite always) the least useful way to deal with critique. The best and most useful thing is to hear and understand what others are seeing in the work, and to a consider it even if it doesn’t mesh with my own perspective. In the end, I can choose to accept or not what I hear, but hearing it is incredibly useful and important.

If you are fortunate enough to have perceptive, knowledgable, sympathetic photographer friends, I urge you to try to get together and try this, and to stick with it long enough to allow the process and the relationships to grow. (And thanks to any of you in the group who are reading this!)

Motion blur abstract of Manhattan traffic

OK, here we go! I’m about to share a string of urban photographs, many of which are from New York City, where I spent slightly more than a week in early August. We were there for several reasons. My wife was attending a music conference at NYU. (A conference of oboe and bassoon players, if you wondered.) Her brother and sister-in-law live in Brooklyn and graciously agreed to host us during our stay, and our two sons also live in Brooklyn. For me this meant that I had the better part of a week to simply head out into Manhattan and Brooklyn, going wherever my intuition took me, and make photographs of the city.

A lot of the photographs fit into the street photography genre — which may seem a bit perplexing to those who know my landscape and nature photography — but this first one is more of an abstraction, created my means of a slow shutter speed and camera motion, most likely as I was crossing some busy street in midtown Manhattan.
