Thanks for that post Dan. This makes sense, there are too many variables between printing sessions that can change the results. Developer age, developer temperature, dilution, paper age, different emulsion, enlarger bulb age, different enlarging lenses.. etc. Notes from a printing session just get us close in the future but I believe ultimately each time we begin to print a negative again we still have to find the correct contrast and exposure for our given variables.
