Lamp, the ‘UFO Building” at Night

February 16, 2011 G Dan Mitchell Leave a comment

A lamp casts a shadow in bright artificial light in a night photograph of the wall of the ‘UFO Building’ at Mare Island Naval Shipyard.

The first time I photographed the side of this weathered and peeling building and Mare Island Naval Ship Yard, I didn’t see the feature that gives this building its informal name. I’ll be that you can though, right? Due to a lucky alignment of this small exterior lamp (which appears to be non-functional) and some nearby sodium vapor lamps, the lamp casts a shadow on the corrugated wall of the building that has a striking and easily recognized shape!

It may not immediately be apparent that this photograph was made at night in very low light. However, a look at the lighting should make it apparent that this cannot be daytime light. Note that the lamp that creates a shadow to its right… is also getting some nice illumination from the right side! One of the fun things about shooting in an industrial location like Mare Island is the amazing mixture of lighting sources. Though it wasn’t much of an influence on this night, the full moon can provide light that is color balanced pretty much like daylight… only a lot dimmer. The sodium vapor lamps that light this area (they are common in street lamps) produce a strongly yellow or yellow/red light. Occasional fluorescent or tungsten lamps provide yet more color variations. In the end, it is just about impossible to say what kind of color balance is “real” – and doubly-so since the actual shooting conditions are near darkness. The only reason that images like this look daylight-bright is because they are typically the result of long exposures. In fact, this one was relatively short at just over a minute. Somewhere in the 2 to 5 minute range is perhaps more typical.

The crazy lighting is apparent in this image if you look a bit more closely. As mentioned above, there is cross lighting here from both sides of the frame. While the strongest light comes from the left (and creates that UFO shadow) there is also significant light from a bit further away to the right. You may also be able to see that the in some areas the shadows created by light from one side are filled in by garishly colored lights coming from the other directions – see some of the very yellow areas along the sides of vertical boards and along the ridges of the corrugated wall.

Bird, Flooded Fields

January 31, 2011 G Dan Mitchell 4 Comments

A bird wades in a flooded Central Valley winter field in front of a receding line of power poles and some farm buildings on a levee.

This is (yet another!) photograph of the flooded fields along a country road near the Cosumnes River in California’s Central Valley. I was shooting almost directly into the sun through remaining fog and haze near the middle of a winter day. The building sits on a levee between the fields and the bird was kind enough to pose for me while I made the photograph.

Given one of the subjects subject that I’ve been discussing at the blog during the past few days, it seems reasonable to point out that this image involved significant work during the post-processing phase – what we used to refer to as “the darkroom,” but which we now refer to as “photoshop.” I used a variety of techniques to push this image towards what I had in mind – a very high key interpretation that I hope evokes the sensation of looking into a backlit hazy atmosphere that is so bright that you can barely look at it. (In fact, it was very much like this when I made the photograph – as you can see it required a 1/1000 second exposure at f/8 and ISO 100. That’s bright!) In general I brought the overall brightness up to nearly pure white in the lightest portions of the image, and I employed some other techniques to lower the amount of contrast in the sky yet keep the building, the poles, and the levee fairly dark. Although all of this was accomplished in the “digital darkroom,” all of the processes are equivalent to those that might have been applied by photographers working in the traditional darkroom.

Central Valley Sky, Winter

January 30, 2011 G Dan Mitchell 4 Comments

Thin winter clouds drift above farmland, Central Valley, California.

Photographing these beautiful winter clouds above the California Central Valley near the Cosumnes River between Stockton and Sacramento involved a certain amount of luck. For the most part it had been an extremely foggy morning – so foggy that at a few points early in the day I simply couldn’t find anything to shoot. Eventually the light began to filter down through the tule fog and I had some good luck shooting further up the valley at the Cosumnes River Wildlife Preserve.

At a certain point as the fog begins to thin it goes through a phase that is not so photographically compelling. The very thick fog can be quite interesting, and the light can be very special just as the sun starts to force its way through the fog as it starts to clear. But they there is a period when it is sort of sunny and sort of foggy, and but perhaps lacks the best aspects of each of the two conditions. That is how it was at about the time I left the Preserve and started back down the valley on my drive home.

Much earlier in the morning I had visited this side road near a bend in the Cosumnes River, so I decided to try it again since it was only slightly out of my way on the return drive. I drove slowly all the way to the end of the side road – to where it runs into the levee at the river – and then turned around to start back. I saw lots and lots of waterfowl, including impressive sandhill cranes and beautiful white egrets, but they were all too far from the road or in areas that didn’t provide the right kind of background. Near these flooded fields I stopped to consider trying to photograph some of the birds, changed my mind, and instead decided to see what I could do with these buildings, the flooded fields, and the sky. It was my luck that this final stop coincided with the near clearing of the fog and the appearance overhead of these wonderful clouds.

Urban Residential Buildings, Sidewalk and Street

January 2, 2011 G Dan Mitchell 3 Comments

Facades of residential buildings along a hilly street in downtown San Francisco.

With all of the landscape and nature photography I’ve posted recently, I figured it was time for something different. This is a street scene in San Francisco I photographed on a quick walk on an early March day in 2010. Many of the other photographs I made in this area included people, but it this one I wanted to isolate the fronts of the buildings, especially the contrast between the relatively fixed-up one on the left and the more weathered one on the right.
