Four pink apartment doors with steps and white columns in the Mission District, San Francisco, California.
Walking in an area like the Mission District, I begin to see many things that would otherwise completely escape my notice. Although I’m sure I’ve seen them before, I recently became away of the prevalence of these building entrances with rows of four nearly identical doorways – this must have been some sort of common building design in San Francisco at some point. Here, as is also fairly common, the colors chosen for the paint were a bit unusual.

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.
Night photography of brick and concrete buildings under artificial lighting with star trails at the Mare Island Naval Shipyard, Vallejo, California.
The Mare Island night photography well has still not quite run dry – so here is one more from my February 6 shoot there with The Nocturnes. I spent a fair amount of time poking around the spaces near this brilliantly lit concrete building and the darker brick building beyond, photographing the two buildings from various angles and directions. The contrast between the artificially lit plain concrete walls of the foreground building and the darker and more textured brick walls of the further building was striking, and I’ve been intrigued for some time by the reflections and glow of the windows up high on the roof. This exposure was long enough that the high clouds moved and created the linear blurred shapes you see in the sky, interspersed with subtle but numerous star trails.

Tower, buildings, and power plant smokestack along Nimitz Avenue, Mare Island Naval Shipyard, Vallejo, California.
One more, and perhaps the last, in the current series of Mare Island night photographs made with The Nocturnes during the first weekend of February. This scene is one that is well-known to Mare Island night photographers – a row of industrial buildings in the “historic core” of the old shipbuilding facility where huge overhead steel structures run between the machine shops and the old docks. In this photograph I decided to more or less shoot through the base of one of these giant towers. The scene is illuminated by bright and colorful artificial light and the photograph required an exposure of about a minute and a half. (I cheated and shot the 5D2 at ISO 200.) Though they may be hard to see in the small jpg, some star trails are visible in the sky near the smokestack of the old power plant.
