Ship Yard Structure, Night

Ship Yard Structure, Night

Ship Yard Structure, Night. Mare Island Naval Ship Yard, Vallejo, California. August 30, 2009. © Copyright G Dan Mitchell – all rights reserved.

A towering ship yard structure against fog lit by artificial lighting at the historic Mare Island Naval Ship Yard, Vallejo, California.

An explanation of the colors in this photograph is probably in order. If you had been there next to me, looking up at the sky past this tall steel structure, you would not have seen colors that looked like this. It was, of course, dark out! You would have noticed a glow coming from the base of the fog clouds that were overhead, but it would not have seemed to have much of a color beyond a certain “warm” effect.

However, once I extend the exposure time so that I get a “normal” exposure in the camera (a bit more than three minutes in this case) light and color that are not visible to the human eye become visible to the camera. During RAW conversion I did not significantly alter the colors – these are what ACR refers to as “as shot” color balance. So we get this wild, luminous effect in the fog clouds and the brightness of the light on the structure becomes similar to that of daytime light… except the colors are different and many of the shadows come from sources that would be impossible in a daytime exposure.

Aspen Grove, Morning, Lee Vining Canyon

Aspen Grove, Morning, Lee Vining Canyon

Aspen Grove, Morning, Lee Vining Canyon. Sierra Nevada, California. June 7, 2009. © Copyright G Dan Mitchell – all rights reserved.

Early morning backlight filters through the green leaves of spring aspen trees to fall on meadow grasses in Lee Vining Canyou, California.

My posting sequence has been a bit confusing lately, I’ll have to admit – I’ve gone back and forth among photographs from Seattle, the eastern Sierra, Yosemite Valley, and more. Now I’m going back to the early June Yosemite photographs to post a few that I did not get to right away. This is one in that group. This is another part of the same small aspen grove in Lee Vining that I photographed in early June when the new meadow grasses were just coming up and the trees still retained some of the new growth color. I had stopped to photograph this grove in shadowed light, looking for the soft diffused effect that this creates. I had just about finished shooting this grove when the sun began to rise above the canyon walls and the first direct light filtered among the trees.

Detail, AT&T Park

Details of the construction of AT&T Park including lamps, stairs, and signage – with the San Francisco Oakland Bay Bridge in the distance.

This photograph was made near the top of the ramp to the upper deck of the SF Giants AT&T Park along the side facing the San Francisco Bay. Visible beyond the backside of the ballpark sign are the towers of the San Francisco Oakland Bay Bridge in the twilight.

Shipyard Structure and Star Trails

Scaffold and Star Trails

Shipyard Structure and Star Trails. Mare Island Naval Shipyard, California. February 7, 2009. © Copyright G Dan Mitchell – all rights reserved.

Shipyard scaffolding illuminated by artificial light and moonlight with star trails – Mare Island Naval Shipyard, California.

One more night photograph from Mare Island, this one being the last frame I exposed before my shutter went to shutter heaven. (Well, actually it went to the Canon Factory Service Center a day later…) This was shot with the camera pointing almost straight up, with the north star just outside the frame at the lower right, and the star trails rotating around that position. The illumination is from a combination of light from the nearly-full moon and nearby artificial lighting – and a very long exposure. I don’t understand exactly how this massive steel structure was used, but it is part of the shipbuilding facilities at the historic Mare Island Naval Ship Yard. These structures tower over the old shops and other buildings at the facility.
