A Photograph Exposed: A Tale of Light

11 Comments

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

On the weekend of June 18-19 of this year I made a point of getting to Yosemite so that I could photograph the high country on the first day that Tioga Pass Road was open for the season. On a shoot like this, my subjects range from some that I planned to shoot ahead of time to some that were completely unanticipated. Among the many things that might affect my decisions is the light itself, and this is a story about that light… and perhaps a few other things, too.

I had driven to the park very early on Saturday morning and after photographing straight through the morning I finally made it over the pass and headed down to Lee Vining Canyon to find a campsite for that night. After getting up at 3:30 a.m. and driving to the Sierra from the SF Bay Area and then shooting all morning, I was exhausted! I pulled into the first available site, paid my fee, and promptly fell asleep in the car for perhaps an hour. When I woke up I set up my camp and at about 3:00 or so headed down to Lee Vining to get some “dinner” – on “photographer time,” dinner tends to either be very early or very late, and on this day I made it early so that I could be back up in the park well before the “good light” started.

Heading back up to Tioga Pass after my mid-afternoon dinner, I had a few subject ideas in mind. Tuolumne Meadows itself was one possibility, and I knew that I wanted to watch for any cascades or creeks that would be flowing in the spring snow-melt conditions. Tenaya Lake was another possibility, and a client’s interest in photographs of Mount Conness had me thinking about the possibility of a photograph from Olmsted Point that included ice-covered Tenaya Lake and this peak.

Backpacking and Photography

Leave a comment

This is the time of year when many of us find our thoughts turning the the upcoming backpacking season. (My home range is the Sierra Nevada, where I have backpacked for decades.) During the past week or two I’ve seen an upsurge in discussions of and questions about photography and backpacking. Several years ago I began posting annual updates on my approach to photography in the backcountry: “Backpacking Photography Equipment.”

Borders and Watermarks

2 Comments

From time to time people ask about the border around my photographs and the inclusion of various text elements within them. Since the question came up again recently I thought I’d explain.

First, borders and watermarks and all the rest are an intrusion in an image, and we would all prefer to see photographs without those elements – preferably in the form of beautiful prints. Prints are the target output for my photography, and online versions are merely stand-ins for the prints. In an ideal world, it would be lovely to be able to share photographs online in an equivalent form.

However, I have to balance my desire to share with the realization that being overly innocent about these things is unwise.Opinions about this vary widely — ranging from those who feel fine about putting full size photographs out there “as is” to those who won’t share anything online at all. My position lies between those extremes. I think that it is possible to enjoy my photographs as they are presented on the web — at least that’s what people tell me! I also understand that no technique can completely thwart the bad guys. So I have arrived at a balance that works for me.

I do several things with photographs that I release “into the wild” in electronic form: Continue reading Borders and Watermarks →

Myth: Diffraction and Motion Blur Worsen With More Megapixels

9 Comments

They don’t.

Another post that I wrote just before this one (“Why Your 21MP File “Looks Softer” Than Your 12MP File at 100%“) explains why pixel-peeping* photographers might imagine that cameras with greater photosite density (e.g. – “more megapixels”) might produce “softer” photographs, based on what they observe when they compare 100% magnification images on the screen. These cameras do not produce softer images – the results will either be equal to or better than those from lower photosite density cameras in this regard. You can follow the link to read the original post.

A reader wrote and suggested that perhaps the images from the camera with greater photosite density really are softer, but the cause is a greater susceptibility to diffraction blur or motion blur.

No. Neither is the case.

These are two additional misconceptions that can be fed by (yet again!) pondering 100% magnification crops on the screen without thinking through the actual (non-) effect of what you see there when it comes to actual photographs.
