[ TREE ON PACIFIC COAST ]
This photo is almost identical to the one at the beginning of the article. It was made on the same roll of ISO 400 film and developed normally. But it was taken at my personalized film-speed rating of 200, not ISO 400. The ISO 400 shot is a full stop underexposed, resulting in a weak print with no true blacks. The ISO 200 shot is properly exposed and has strong blacks. Proof can be seen in the sprocket holes below the image -- they are no blacker than the surrounding clear film. The print was given the minimum enlarger exposure required for maximum black through the clear film.
