Powerplant, Railroad Avenue – Mare Island Naval Shipyard

March 7, 2010 G Dan Mitchell 2 Comments

“Powerplant, Mare Island Naval Shipyard” — Power Plant building and other structures along Railroad Avenue at the historic Mare Island Naval Shipyard, Vallejo, California.

(Note: This post has been updated to include a newer interpretation of this photograph, as seen above. The original is also included later in this post.)

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.

Nimitz Avenue, Tower and Buildings

February 18, 2010 G Dan Mitchell Leave a comment

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.

Brick Wall and Fence, Railroad Avenue

Black and white photograph of a night scene on Railroad Avenue at Mare Island Naval Ship Yard with cyclone fence, brick wall, pipes and tank, window, and speed limit sign.

I was thinking about the Panocturnists group when I made this photograph at the Mare Island Naval Ship Yard during the first weekend of February. The location is in many ways pretty mundane – one of the first areas that most first-time Mare Island night photographers shoot near the entrance to the so-called “historic core” of the site, and nothing that would warrant a second look during daylight hours. Not surprisingly, most photographers here are initially attracted to a nearby turnstile or to the massive steel structures overhead. I’ve shot here enough now that, while I’ll still shoot those subjects, I usually look for less-obvious subjects that I may not have tried previously. So while some new folks photographed right behind me I decided to see what I could do with the street light-illuminated fence, wall, and collection of pipes in this corner. (And, as the long exposure was underway I was able to help out the first-timers… :-)

Chairs and Tables, San Francisco Bay

July 6, 2009 G Dan Mitchell Leave a comment

Chairs and tables on the sidewalk next to a fence along the Embarcadero with an old pier and San Francisco Bay beyond – San Francisco, California.

I found this slightly odd scene along The Embarcadero between South Beach Harbor and the San Francisco Ferry Building. These chairs and tables were cabled together, waiting to be set up for outdoor seating at a small restaurant. I think the range of brown tones in the image is interesting – not just the chairs and tables but also the old pier extending out into the San Francisco Bay.
