I'll chime with my tech pan formula. Rate at 80 and develop in diafine. Develope in the "B" solution for 45-60 seconds. 45 seconds will print with a 2-21/2 filter(condesers). 60 seconds will print on 2 with a diffusion enlarger.(posted 8644 days ago)Advantages;
Diafine works with all films, also outstanding for T-max 100.
Time in the solutions other than the "b" for tech pan is not critical
No need to adjust for temperature as long as it is between 70 and 85 F
Agitation is not critical. In other words, the only way you can screw up the negatives is to either miss the exposure or leave the top off the developing tank when you turn on the light(Did that earlier this week and lost a roll of grandchildren pictures-I've only been doing darkroom work for 50 years.)
A batch lasts for up to a year with replenishment from unused stock solutions.
Disavantages
No +/- N development.
No other disavantages.
KISS!
