Abstract |
Equally exposed films were developed in 26 automatic processors. Films were developed in 22 of these processors, one film per week for 3 consecutive weeks. The percent standard deviations of the film base-fogs, relative speeds, and average gradients were respectively 18, 12, and 4 percent. Films were developed in the other four processors on a daily basis for one-month period. During this time, two of the processors required major servicing because of mechanical and chemical malfunctions. The percent standard deviations of the base-fog for the films developed in these two processors were 39 and 51 percent. For the other two processors, the percent standard deviations in the base-fog were both 11 percent. (Author) |
