I'm dipping my toes and readying to plunge. I want to move into 4x5" photography. Can anyone recommend a book or web site that is a good general introduction to the equipment needed both for shooting (I want to go the field camera route - maybe a crown graphic) and also want to process my own BW film. In particular what would be the recommended equipment for processing the film. I'd like to go a route that would hopefully let me get away with a dark changing bag and avoid the need for a dark room.
