A notch code is a set of notches or recesses cut into the edge of a piece of sheet film to provide a tactile way to identify the film brand, type, and processing chemistry (e.g. black and white, color negative, or color reversal) in the dark. It enables photographers to identify the emulsion side of the film when loading sheet film holders, and ...

Therefore, for 24 gallons of Indulin AA-86 would be diluted with water into 8,000 gallons, a volume that is a standard storage/mixing tank ...

Water on the emulsion side will ...
