Kodak T-max 100 @ISO25 developed in Jay DeFehr's 510-Pyro
Real film speed of Kodak T-max 100 in 510-Pyro is ASA 64!
For night shots I did a contrast adjustment of exposure @ ISO 25 and development of N-2.
Finding the right exposure for night shots is quite simple.
1. Overall contrast is quite high, so: Pull, don't push!
2. Measure for the high-lights (street lamps) and define them as Zone VII. Then open 2 stops (or increase exposure time accordingly) for shooting at Zone V.
How far the lamp lights reach out depends on how strong you pull.
3. Take reciprocity failure into account.
Development in 510-Pyro (100 ml TEA, 10g pyrogallole, 5g ascorbic acid, 0.375g phenidone)
11 mts @ 22°C
wherefrom the first minute is initial agitation plus 1 inversion at 10th. minute.
