Powerplant, Railroad Avenue – Mare Island Naval Shipyard

March 7, 2010 G Dan Mitchell 2 Comments

Night panoramic photograph of the powerplant building and other structures along Railroad Avenue at the historic Mare Island Naval Shipyard, Vallejo, California.

This is a bit of a first for me – a night photography stitched panorama. This image is composed of two separate exposures which were aligned and “stitched” into a single image in post. (As such, it could be a very large print!) Shooting from an elevated position, I shot almost directly north (as you can tell from the star trails in the larger version). The view looks up Railroad Avenue past the iconic power plant building with its smokestack that is visible from all over Mare Island.

I’m usually a bit casual about exposure time with long exposure night photographs. It isn’t that I don’t care – it is just that one has a ton of leeway when it comes to the very long exposures I typically use. For example, on a 3 minute exposure you would have to be off by three minutes to overexpose by one stop! So rather than use a stopwatch or an automatic timer I just count to myself. I’m usually will within a 10% error, and that is good enough. However, when stitching “good enough” often isn’t. The separate component frames really need to be quite similar, so in this case I resorted to using my watch to get relatively accurate 90 second exposures.

Another interesting factor in night photography is illustrated in this photo, namely the wildly varied colors of the light sources we deal with. There are three dominant sources in this image. The overall illumination comes from the full moon, which is quite similar to day light in terms of white balance. On the near wall of the brick power plant there is very “hot” and saturated yellow/red tinted light, probably from sodium vapor lamps. Near the left end of the image is an old wooden building that is illuminated by very green light, which I believe comes from mercury vapor lamps. I often chuckle a bit when people speak of “white balancing” the color in a scene like this. If you pick one source for your white balance you’ll throw the others even more out of line. My philosophy is usually to just go with what looks right!

Finally, the idea of making the stitched panorama came from the recently started Panocturnists web site, begun by people connected with The Nocturnes, the San Francisco Bay Area night photography group. I was intrigued by the idea of creating panoramic night photography, and I’ve done a few images along these lines on my two most recent visits to Mare Island.

Horsetail Fall, Early Evening

March 5, 2010 G Dan Mitchell 2 Comments

The silver strand of Horsetail Fall and water reflecting on surrounding cliffs in late afternoon light, Yosemite Valley, California.

I’m thinking it is pretty nearly impossible to make a truly original photograph of Horsetail Fall – though I won’t completely rule out the possibility.

In any case, here I decided to start photographing the February spectacle a bit before the colorful sunset light showed up. At this point the beam of light on the cliff face around the fall is a bit larger, lighting the rocks to the right of the fall as well as the fall itself. During this season there has been enough precipitation and the weather had warmed enough to not only get Horsetail flowing but to also create some seepage down the face of the cliff next to the fall. As a matter of fact, the reflections from this wet rock caught my attention more strongly at first than did the fall itself. A second process was at work here as well: a stiff breeze from the west was blowing across the path of the falling water, catching it, and blowing thin clouds of spray across the buttress to the left of the fall itself.

I have posted several short articles on photographing this seasonal Yosemite Valley icon:

“Thinking About Yosemite’s Horsetail Fall” (2012)
“Photographing Horsetail Fall – Random Thoughts About Photographing an Icon” (2011)
“Horsetail Fall – It’s That Time Again” (2011)
“Thinking of Photographing Yosemite’s Horsetail Fall?” (2009)
Search results for Horsetail Fall at my blog (results will include the above-listed articles and more)

One of the best sources of current season information about the Horsetail Fall photography potential is photographer Michael Frye, who frequently posts general information and updates each winter.

Belmar Meat Market, The Mission

March 3, 2010 G Dan Mitchell Leave a comment

Photograph of street scene in the Mission with man walking on sidewalk, Belmar Meat Market sign, and other urban elements – San Francisco, California.

Another Mission District street scene – a matter of spotting an interested set of urban storefronts, composing the shot, and then watching for the right person or persons to walk through the frame. I’m fascinated by the complexity of these urban scenes and by the individuality of the storefronts in this type of place – each one seems to reflect something about the surrounding community and the people who live there. In this one certain compositional elements and color relationships also caught my attention.

Wall and Signs, The Mission

March 2, 2010 G Dan Mitchell Leave a comment

Brightly colored yellow and blue wall with red and white sign and restaurant window with food photographs, The Mission, San Francisco, California.

Another photograph of the subject I posted earlier – some very colorfully painted walls in the Mission District of San Francisco. While the previous one was a tighter crop in “landscape” orientation, I composed this one to show more of the vertical lines and to include the window-posted menu on the right side. Kind of makes me hungry just to look at it!
