A Photograph Exposed: “Two Rocks, Morning, Racetrack Playa”

(“A Photograph Exposed” is a series exploring some of my photographs in greater detail.)

Two Rocks, Morning, Racetrack Playa - Black and white photograph of two "moving rocks" on the Racetrack Playa at Death Valley National Park. Morning light with unusual clouds, and the Grandstand in the distance.

Moving rocks, lenticular clouds — morning on the Racetrack Playa.

This photograph from Death Valley’s Racetrack Playa is one of the first I made when I began photographing this landscape seriously, and it remains one of my favorites from the park — yet it also carries a flaw that I’ll describe below.

My first visit to Death Valley National Park had been about seven years earlier at the very end of the previous millennium, when I was one of several adults accompanying a group of middle school and high school students on a visit that was to include a short backpack trip in the Cottonwood Canyon area. The story of that trip deserves its own article, one that would include snow, near-hypothermia, winds that blew down tents, a retreat from the pack trip, an attempt to hike down the upper portion of Death Valley, water shortages, a dust storm, a dangerous situation with a bus, and more.

I’ll never forget my first view of Death Valley on that first visit. We arrived in the park after dark, stopping between Towne Pass and Stovepipe Wells at a small campground a few thousand feet above the valley floor, where we set up in the darkness and went to sleep. Having never seen the Valley before, the next morning I unzipped my tent and stepped outside to see the stupendous “oh wow!” landscape of Death Valley and the mountains on the far side in the beautiful morning light. I was hooked, and I’ve been going back annually since then. Continue reading A Photograph Exposed: “Two Rocks, Morning, Racetrack Playa” →

Canon EF 100-400mm f/4.5-5.6L IS II Lens — A First Look

(Note: Updated 12/24/14 to add thoughts about “who should buy” this lens.)

Canon recently released the successor to their venerable 100-400mm telephoto zoom lens, the new EF 100-400mm f/4.5-5.6L IS II lens. I have relied on the older model for some time now… but my copy of the new lens arrived a few days ago. Now that I have used it for a day of wildlife and landscape photography I would like to share some first impressions

First, a few technical details. The new lens covers essentially the same range as the older model — a focal length range of 100mm to 400mm and a variable aperture range of f/4.5 (at 100mm) to f/5.6 (at 400mm). Both lenses use a zoom mechanism that extends at longer focal lengths. However, there are some technical differences:

Misplaced Focus (Morning Musings 12/3/14)

From time to time I adapt things that I wrote elsewhere and re-share them on the blog. The following is something I contributed to a discussion about a question from a newish photographer who wondered how important it would be to upgrade his camera. 

I’m all for better image quality — which contemporary cameras, software, and printing processes provide in spades. And there is no question that, all else being equal, a photograph captured on a larger film or sensor format can potentially resolve more detail, and may improve other image parameters including dynamic range and noise.

As they say, “So stipulated.”

But the question (which was about choosing a sensor format) deserves a more nuanced and contextual answer than that. Fortunately, the most accurate and useful answer involves quite a bit of that nuance. I think it really comes down to something like, “Will replacing my cropped sensor camera with a full frame camera make my photographs look better?”. The best answer begins with, “It depends.”

As to the question (which also came up in the original discussion) of what is important in a photograph, image sharpness is not unimportant in many cases. (Though there certainly are photographs whose “goodness” is perhaps at least partially because they are blurred — softness and blur are not always things to be avoided.)

I think the issue in photography discussions is frequently about the balance among issues that affect the quality and effectiveness of a photograph. Here, it is not uncommon for some folks to exhibit a misplaced focus on the technical stuff, accompanied by insufficient attention to other things that are more important to their success as photographers.

Too Many Aspens!

Yesterday I realized that I had sort of forgotten a huge batch of aspen photographs from this fall in the eastern Sierra Nevada. How can one “forget” a big batch of such photographs, you ask? I simply became busy working on several other projects and after I moved on to them I stopped thinking about the earlier work.

I have so many of them — with more to come! — that I’m not going to string them out and post one at a time. Instead, here is one big batch of them all in one post. To save typing, all are from the eastern Sierra Nevada in October 2014
