IMPROVEMENTS IN OR RELATING TO PHOTOGRAPHIC PROCESSING |
摘要 |
In photographic processing apparatus, by-products are produced due to the chemical reactions which occur during the processing of photographic materials. It is known to remove some of these by-products in accordance with the area of photographic material processed and a knowledge of the average level of production of the by-products. This leads to inaccuracies in maintaining a fixed level of the by-products in the processing solutions. Described herein is a method of controlling a subsystem which removes by-products from the processing solutions by using data relating to the exposure given to a photographic material in the printing stage of the processing apparatus to calculate the amount of by-products produced so that they can be exactly removed from the processing solutions. |
