Structural elements at the High Line Park, Manhattan

Taking a cue from the music-related title of this photograph, I suspect you may have noticed that my photographs cover a wide range of subjects. When people ask me “what I photograph,” probably expecting a short answer like “landscapes” or “portraits” or “street,” there can be an awkward moment while I consider how to answer. I don’t photograph just one thing… any more than a composer would choose to write only, say, minuets. There is more than one thing to express, so more than one approach is necessary. If anything, my photographs are about… how I see the world photographically.

I won’t try to explain the entire “consonance and dissonance” connection here, except to point out that these terms have multiple meanings. One basic idea is that something is consonant in music if it “sounds nice” and “dissonant” if it doesn’t. But a more interesting idea relates to something that seems static and “settled” (consonance) versus something that seems restless and striving (dissonance). Taken one step further, the tension created by dissonance often propels us toward consonance… and consonance can resolve that tension.

I made this photograph at about the same time as another one that I posted recently — it also featured a close-up view of the weathered structure of an old steel bridge with rivets, colorful stains, and lots of weathering.

Whether the specific location is all that important is debatable, but I made the photograph on the “Steel Bridge” (that’s actually its name), over the Willamette River in Portland, Oregon. This is an old and quite busy structure, and it is full of fascinating little vignettes.

This might be the most unimaginatively named steel bridge in the United States — as far as I can tell it is actually called “Steel Bridge.” Which it is. The bridge crosses the Willamette River in Portland, Oregon, where its double-deck structure (with a center section that can be raised) carries trains, cars, pedestrians, bicycles, and rapid transit across the water. When we visited we joined the pedestrians, which gave me a chance to look at the structure close up.

Old distressed and weathered structures like this intrigue me, and I know I’m not the only photographer who has this interest. Sometimes I imagine the contrast between some engineer crafting very careful and precise design drawings of the structure and its smaller elements, producing materials that reflect the conceptual perfection of such structures… and the real-world reality the creeps in over the long life of such structures. The latter is visible here in the multiple layers of paint, now marked by stain patterns and split open to reveal rust.

Towers and Brick Building, Full Moon Light. Mare Island Naval Shipyard, Vallejo, California. February 27, 2010. © Copyright G Dan Mitchell – all rights reserved.

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!
