Kodak Professional TMax Film Developer – 1 Liter is a liquid concentrate black and white film developer helping to produce expanded shadow detail and maintain accurate tonal reproduction with normally processed and push-processed roll films. This concentrate is a buffered solution designed to be diluted with water at 1:4 for easy mixing for small tank and rotary tube development. This 1 liter bottle contains enough concentrate to make 5 liters of working solution.
The Brownie Camera Guy says:
I use TMax developer when processing TMax films when the finest grain is mandatory. It produces the finest T-Grain results. If a negative must be scanned and printed large, especially for work where sharpness, shadow detail and non-grain is desired, then TMax film and TMax developer is the combination to use.
