ABSTRACT:
A film developing apparatus includes an exposure section for effecting a standard exposure on a photosensitive film under a predetermined condition in a manner similar to that for exposing a control strip. The apparatus further includes a transfer path for transferring the exposed film for development, a densitometer for measuring the density of the developed film, and a device for displaying the condition of the processing solution which is determined based on the measured density. The standard exposure is effected on an unexposed film which is specially provided for the standard exposure, or on a part of an ordinary film with which pictures has been taken. The plural conditions may be set for the density measurement and for the standard exposure. The film developing apparatus is provided with a sensor for detecting the kind of a film to be exposed, and for selecting conditions based on the kind of the film.
