I am using Kodak chemicals and normally I process at 94 degrees using a Jobo CPE-2 processor. I wanted to try batch processing at room temp using a vertical slot processor. I developed at 68 degrees for 2 minutes then 2 minutes wash then 2 minutes BLIX then 5 minutes wash. I added 5 Yellow as a correction and added 1/4 F stop more time in exposure. The resultant prints at room temperature lack the contrast that I am used to using the Jobo at 94 degrees. It is normal to have reduced contrast using RA-4 at room temp?
