Turnstile Shadows. Mare Island Naval Ship Yard, California. February 12, 2011. © Copyright G Dan Mitchell – all rights reserved.

Shadows cast by sodium vapor lamps shining on old turnstiles at Mare Island Naval Ship Yard.

This old row of abandoned turnstiles stands at the entrance to an alley through which we almost always walk as we begin shooting in the core area of the historic Mare Island Naval Ship Yard near Vallejo, California. It seems odd to see the structure here since now one can just walk around them, but I suspect that this area must have been somewhat secure at times since military ships were built here.

This isn’t an easy subject to photograph. Several of us were talking about how we have struggled to find a composition built around the turnstiles. I have one other photograph that I made a few years ago that I think works pretty well. In that one I aimed a bit higher and let the metal structure pretty much fill the frame, and I also ended up making it a black and white image. (It was used as a cover for a book at one point.) But on this evening a few of us were staring at the turnstiles again and remarking that there must be more photographs in there… somewhere… but that we are still trying to find them.

I thought it might be interesting to make the long and complex patterns of the shadows fill most of the frame, so I moved back just a little and pointed the camera down so that just a portion of the turnstile structure appears at the top of the frame. This also helps with a couple of technical challenges: the bright lights beyond the structure create a tremendously large dynamic range in the scene, and it can be difficult to keep some distracting background elements (like a stop sign!) out of the image. The garish yellow/orange light is from a large sodium vapor lamp that sits above the intersection on the road in the background. That coloration is part of what made me choose to make the previous photograph of this subject black and white, but on this night I decided to go with the color.

The final image is a blend of two exposures. The shorter one was selected to avoid blowing out the brightest areas in the upper part of the frame, and the longer one let me keep a bit more detail in the shadowed asphalt foreground.
