Here in Germany a common developer for TP is Tetenal Neofin Doku, but it is around $1 per film. So for testing the film I use good old Rodinal 1:100 for ~7 mins, ISO 25. I would not worry too much about grain, as I did a 15"*20" and had too much detail to think about looking for grains.(posted 8903 days ago)Regarding filters I did test TP with Kodak 25 using a Philips red/infra-red light source. As the sensitivity of TP for red seems higher than the TTL metering of the camera, ISO should be rated 32-40. Log density was between 0.1 and 1.7 for Zone 0 and Zone 10.
