Use of Tmax RS B&W Develeper


from Marin County, CA  -  Photo Enthusiast

I have used TMax developer for years with TMax 400 film at a dilution of 1:9, developing one roll in a 16 oz. tank for about 11 minutes for one use only. After each roll, I dispose of it, never replenishing or reusing it. When only TMax RS is available I Simply use Part A in the same way and disregard Part B. The results are the same. rs

Questions about this item:

Fred D  I develop 2 films at a time and per week. I use 5 to 6 ounces of the regular TMAX at a time. What are the proportions for Tmax RS? How about bottle B? Do you have to use bottle B?
ROBERT B  Mix up the T-max developer as per package instructions. use both part A and B as indicated to make a working solution. Use 1.5 oz of T-max RS as a replenisher per 36 exposure role of 35mm T-max film or 1.5 oz per roll of 120 roll film T-max.
Shopper  how does this differ from the TMax developer we've been using for years? why aren't there instructions? why is that B there?
CORTNEY H  This isn't the normal Tmax developer, it is different. There are instructions, but I have to admit, I don't know what they say. My favorite photography instructor got an alternative recipe for processing from a friend using this (and throwing out the instructions) and I tried that recipe and loved it. I'm guessing that if you follow the instructions, you will get good results, but no, this is not the regular tmax developer.
Abigail H  what is the difference between rs developer 1 and 2?
GILBERT J  You mean RS and regular Tmax developer? RS is for sheet & roll film, can be mixed in dip & dunk tanks & replenished. Regular Tmax developer is for roll film only and is a one shot developer
