Altamont Wind Farm

I had tried once before to get a nighttime picture of these modern-day generators, to complement my shot of a more traditional windmill. The proximity to the large population near San Francisco Bay fills the sky with light, and my previous pictures had been washed out. This time I was armed with a light pollution rejection filter and enough time to find this interesting composition.

I rediscovered a characteristic of these filters- they are very angle-of-view sensitive. To see how the film sees this view through the LPR filter and learn more about them, visit this earlier page and more detailed comparison.
