Got three square bottles of this for only the first verse of a short song (10 cents each). Question is, can it still be used for developing 4x5 sheet film? The newer bottles are round but this stuff's in the older 16-oz. square ones; sealed and unopened. No date on these bottles so its age is a big question.
Probably would work but development time would be longer or have to mix a stronger solution.
Just curious. Any suggestions are helpful. Thanks in advance.
