Le seguenti informazioni sono estratte dall'articolo "A few ideas on using Kodak T-Max Films Successfully" di John Sexton.
T-MAX films require no real difference in exposure technique for most applications. One important difference is that the T-MAX films (T-MAX 100 in particular) have greatly improved reciprocity characteristics compared with most other films. Kodak Publication F-32 gives some useful, and accurate, starting points for reciprocity compensation.
This means the films maintain their speed much more effectively with long exposures.
I prefer the following procedures for normal contrast.
T-Max 100 EI-80 T-MAX 1:9 11 min @ 75FThe times below should be good trial data for roll film agitated for 5 seconds every 30 seconds.
T-Max 400 EI-320 T-MAX 1:9 10-1/2 min @ 75F
I use ALL developers one-shot.
This data is for a typical diffusion enlarger.
For negatives to be printed by condenser enlarger reduce the above times by approximately 20%.
In pratica questi sono i tempi da usare in gradi centigradi e per ingranditori a condensatore:
T-Max 100 EI-80 T-MAX 1:9 9 min @ 24C
T-Max 400 EI-320 T-MAX 1:9 8,5 min @ 24c
