Abstract
In order to make various photographic processes more quantitative, we made the photographic processing system which had the computer simulations and the developments of the programs for various photographic processing, the contact printer controlled by a microcomputer, three kinds of automatic processors for development, etc. Photographical density slicing processes and pseudo color processes were fully analyzed and the very useful improvement for these processes were made. Moreover the photographically processed results were consistent very well with the results of the computer silu-lations and analyses. Good advancement on the photographic processing in accuracy and reproduci-bility was attained.
