San Francisco – Decaseconds

Sodium Emission vs. Rayleigh Scattering

2020-Oct-21 adohertyhLeave a comment

We’re not far from the ninth anniversary of the founding of Decaseconds, and I came upon this arresting image of Berkeley Marina, the Marin Headlands, and the Golden Gate Bridge (never before published here) while searching for just the right anniversary shot. I’m fascinated by the way the orange emission of sodium vapor lamps lighting Berkeley (I’m sure now all swapped for white LEDs) matches the Rayleigh-scattered oranges of the winter sunset. The same wavelengths of light, coming from completely different mechanisms.

New Year: Skyline Watcher with Cactus

The year 2020 is here! “Cautious optimism” remains my default lens for the future, but a look back over the photography of the past decade (like this shot from the Molecular Foundry overlooking San Francisco during my sabbatical), I’m feeling a bit excited. The first major upgrade in my shooting platform is planned for 2020 (the Nikon D7000 is getting a well-deserved retirement) and I can’t imagine the improvement I’ll see when I jump an entire decade forwards in camera technology.

Every Detail of the Bay

My favorite view of the Bay Area (and the view that first let me define the idea of the civilization gradient as an element of my photography) is layered up with loads of detail. Down in Berkeley Lab is the building where I worked on sabbatical, and across the Bay Bridge is the completed Salesforce Tower hiding in the marine layer. The differences, particularly from the last time I showed a very similar shot from the spring, are in nature: the high-altitude clouds have been replaced with empty skies and that rolling marine layer, while the green hills have shifted to a dry, highly flammable tan.

San Francisco’s Russian Sunset

I sometimes reprocess older pictures when I find some new approach or something special in an image that wasn’t there before. This picture is a bit different—though I captured it at this time seven years ago, I found that I felt no urge to reprocess any part of it. I was happy with it then—though apparently not enough to post it until now—and I’m impressed with it today.

Fire Trails Apart

As busy as the cities of the Bay Area become, there are the spaces in the fire trails (like the one in the foreground) to get some quiet and distance. There’s an odd orthogonality of the senses in being able to see all of the commotion below with none of the accompanying sound.

Six (Christmas?) Trees Above Berkeley

2019-Sep-13 adohertyhLeave a comment

Two of my past St. Lawrence University students are working on their Ph.D.s at Berkeley and I discovered yesterday that one was giving her Graduate Research Conference (Berkeley’s version of a thesis defense, but earlier) while the other was in the audience. I’m very proud of both of them.
Understandably, this had me thinking about my experiences at Berkeley. In this picture from Grizzly Peak, the perspective folds together Oakland, San Francisco, and Berkeley. In the foreground, look at those gnarled trees—they’re weird but they’ve grown tall. I’ll take that visual metaphor for the grad school experience. I took this picture on Christmas Day in 2016, so I guess that makes these Christmas trees, too.

Pale Cloud City

Marine layer water clusters suspended in the air can always turn San Francisco pale, but the fuzziness of memory also layers over the time when Transbay Tower was under construction.

Under the Span

Far, far out, under the span of the Golden Gate Bridge, boats move through the haze. The extreme distance compression of this 500 mm lens puts the end of the old Berkeley Peer practically beneath the bridge, despite them being on opposite sides of the Bay. Optics are fascinating.

Pastel Reflections and the Red Bridge

Lovely, gentle dusk colors—pinks and magentas and purples and aquas—settle over San Francisco and the Marin Headlands, but it barely touches the bright red (technically International Orange) of the Golden Gate Bridge.

Triple Tower

Sutro Tower has a Neo-Tokyo style at any time of day, but a hazy orange sunset adds a layer of Blade Runner/Cyberpunk 2077 style to the overwatching structure.

Little Path//Big View

2019-May-032019-May-02 adohertyhLeave a comment

I took this picture two years ago, during a wonderful springtime in Berkeley when a rainy winter had made the hills lush and green. The view is enormous, overwhelming: Oakland, San Francisco, Emeryville, and Berkeley all packed into one. I like the contrast of the tiny path on the green hilltop on the left side of the image providing a quiet contrast.
