PinPlus cameras for telephoto pictures
This sires of PinPLUS cameras have a small angle of view, but light from a pinhole into the camera body is 170 degrees in all directions. Therefore baffeling is required to attenatuate the out of film picture light that passes through the pinhole. Otherwise the bounced light will fog the picture, and/or remove any chance of pure black in the picture.
