Optical system for use with a viewfinder

摘要

A film carrier is provided with a film viewing window formed therein and a loop forming device between the film viewing window and a film exposing window. Prior to printing, a film is inspected through the film viewing window to input position and exposure correction data for each frame of the film. The film is adjusted automatically in position in the film exposing window according to the position correction data. At the film exposure window the inspected film is subjected by a scanner only to measuring (to find an exposure) and exposing. To print a half size of 135 film in place of a full size of 135 film, the film carrier is turned 90 DEG , directing the half size of the frame in the same direction as the full size frame and placing the film viewing window on the side of an operator.
