Dear all, I need to relocate my darkroom in a place where i am quite short on place. To minimize the lenght needed for my 3 baths, i was thinking to use a vertical bath. Except for the amount of product i will need to fill the tanks, what will be the issues ? Does it already exists this type of tanks ? I don't know so much about chemical but is it possible that i can have some variation in the development between the part of the paper which will be at the bottom and the one at the top ?
