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.

Towers and Brick Building, Full Moon Light

March 6, 2010 G Dan Mitchell Leave a comment

Industrial towers and brick building under the light of the full moon at Mare Island Naval Shipyard, Vallejo, California.

On February 27, for the second time this month, I visited Mare Island Naval Shipyard to do night photography with The Nocturnes, the San Francisco Bay Area night photography group. (Anyone looking for great resources on night photography should visit their web site. They also offer classes and workshops on night photography.) This was a “Mare Islands Alumni” event, attended by quite a few folks who have done night photography at Mare Island. One of the highlights came before the actual photography began as we met in the museum building and had a chance to view work by participating photographers – the work gets better every time and there was some wonderful night photography on display.

One attraction on this night was the full moon, which appears just above and to the right of the frame in this photograph made near the intersection of 8th and Nimitz Streets, in the heart of the old ship construction area. The was the first subject I photographed – it was something of a “do over,” since I had overlooked some obvious composition problems with the shot earlier this month and wanted to get it right this time. When I originally mentioned that, Tim Baskerville pointed out that I might have a hard time getting the same reflective puddles in the scene, but as luck would have it a good sized storm was just departing and it left great puddles everywhere!

24th and Folsom, The Mission

February 27, 2010 G Dan Mitchell Leave a comment

The corner of 24th and Folsom Streets in the Mission District, San Francisco, California.

This was an afternoon of really interesting light in the Mission District of San Francisco. Although it was mostly cloudy and often gray, at times the clouds thinned and warm, diffused light appeared for a moment or two. One such moment came as I arrived at the corner of 24th and Folsom where this garishly yellow building sat on the corner opposite me and picked up light coming between the buildings.

Anyone who goes to the Mission probably immediately notices that something is “wrong” with this photograph. Where are all of the people and all of the cars!? I saw this composition and set it up – but at first the street was filled with people and cars speeding through the intersection. In fact, during the instant before and after I grabbed this frame there were fast-moving cars in the intersection. (For those who haven’t visited the Mission and who think that this peaceful scene is typical of the area, uh, no. The Mission is a very busy and active place that is usually filled with people.)

North Dome and Merced River Trees, Winter

February 25, 2010 G Dan Mitchell 1 Comment

Black and white photograph of North Dome and bare winter trees reflected in the Merced River near the swinging bridge, Yosemite Valley, California.

After first getting distracted by dawn light on Yosemite Falls – and joining a small throng of other photographers shooting this exact same subject (he writes, somewhat embarrassed… ;-) – I pulled myself together and wandered off along the Merced on this frosty morning looking for scenes that were a bit less obvious. I’m not going to claim that this one is completely non-iconic – I can’t since North Dome, in the upper center of the frame, is a fairly well known feature of the Valley. However, the thing that mostly caught my attention here was the skeletal shapes of the dormant trees along the Merced River and the way they lined up across the scene creating some interesting symmetries and forms against the background of the upper end of The Valley.
