I have developed T-Max100 in TMax RS for about 25 years. I have found that if you use a 1:9 dilution (see John Sexton) the developer will behave beautifully and highlight details will be retained. I was never successful at getting good results with Kodak's recommended 1:4 dilution. Remember to be consistent with times and temperatures since TMax RS responds strongly to any change in processing technique. If you are careful this is a great developer, and the self-replenishing feature makes it easy always to have a fresh working solution. The instructions on the box are now very confusing. I have always just poured solution B into the bottle of Solution A and then diluted that with 9 parts water as needed. The stock solution lasts for a few months after A and B are combined. There is so little of Solution B in the bottle that measuring it would be very difficult. It used to come in a ketchup-like plastic packet that could not be re-closed. Back then there was no doubt that you just dumped B into A. You can also try using it with a water bath for extreme contrast reduction. Just get good at using this developer and you will be very happy. People who complain about TMax RS and TMax developers are not giving them a chance or are sloppy in the darkroom. You're better than they are so you'll get good results.

Use as a replenisher in 1/2 gallon working with other 1/2 gallon as the replenish. Get a good number of rolls out this way but dump after 4 months if not all used up.

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
