Just remember, exposing less (a stop or two, or three) will provide better highlight separation and leave shadows either black or very, very underexposed. That is what you want on pictures like you posted. Of course, with underexposure, development must increase in order to get what you want. What you DO NOT WANT is to give normal exposure and then cook the film in the developer. You will then achieve a nighmare of density and distress. - David Lyga
