Abstract (en)
A photographic printing and developing apparatus includes an exposure section (1) in which a standard exposure is effected on a photosensitive material (4) under predetermined conditions in a manner similar to that for preparing a conventional control strip. The apparatus further includes a device for measuring the density (15) of the developed photosensitive material, and a device for displaying (7) the condition of the processing solution which is determined based on the measured density. A negative film is prepared for the standard exposure. The apparatus is provided with a control section which selectively uses different light sources for ordinary printing and for the standard exposure. The control section reads in the measured density of the photosensitive material (4) after developing process, and calculates the condition of the processing solution based on the measured density. It is judged whether or not the condition of the processing solution is within an usable range, and the results of judgment are displayed (7). <IMAGE>
