Railroad picture of the day (second place)
When I'm not trying to plan a picture, I leave my Pentax in full-auto mode so it can figure out the best exposure settings. But one of the things I did with it was to prune down the region that it looks in to figure out how to expose things, because I want to be able to point at an object and have that object be properly exposed no matter what the rest of the photo looks like. This usually works, but sometimes, like when I'm in a car going past this Yellow Menace engine, I don't get the camera pointed properly and the exposure turns out to be not exactly what I'd planned.
This picture was taken at 9am on Wednesday, and it was not even close to as dark and forboding as you might think.
