Out Of The Darkness

This challenge is about taking pictures in dim ambient lighting. On film this was problematic: long exposures suffered reciprocity failure and film ISOs didn't go much above 400 without "push processing." However, modern digital cameras can extract usable images from very poorly lit scenes using long exposures, sensor shake compensation, really high ISOs, noise reduction processing (including stacking), etc. This challenge is for digital images captured in lighting dim enough to start to be a problem for film -- photos that would require an exposure of 1 second or longer with ISO 100 at the aperture setting that you used.
