Now go outside and look at the sky.
Here's a bit of a different view of Nob Hill in San Francisco. This is on Joice Street at the corner with Sacramento looking uphill towards California Street. Joice is a very narrow street, really only a steep canyon between the tall buildings near the top of the hill.
The light conditions were pretty bad as it was an overcast day and it was already late in the afternoon when I shot this picture, but I like the resulting mood and the graininess of the photo. The picture was taken with my Kodak Duo Six-20 on Ilford Delta 100. Click for a larger version.
