I am trying to collect some processing information on Cachet/Maco's infrared film. I would appreciate receiving processing information going beyond the sparse data and developer recommendations given in the film's tech sheet. If you have and tested data, please let me know. Please don't forget to mention the following data:

1) developer, including dilution

2) temperature (20°C, unless otherwise specified)

3) agitation (rotation/cont./30 s/1 min)

4) developing time

Thank you in advance.

Gretings Thomas,

I have used Maco's recommended times with XTOl at 1:3 and found the results seriously lacking. Furter testing has resulted in the following: XTOL full strength at 20C in a JOBO processor at 75 RPM for 5 minutes, no prewash. Plain water stop for 30 sec. and 2 min fix in Photographer's Formulary's TF-4 fixer. 15 min wash and 45 sec in Kodak Photo-Flo, then air dried. The negs curled unlike anything I've ever processed, but produced beautiful results, that easily printed without filtration, or manipulation. My ISO with a Lee 87 filter was 3. Please keep me posted on your findings and I will do the same.

Regards

Diafine works great(but it always does). Follow the directions on the package. I get an EI of 6 with a 720nm Hoya filter

A Hoya R72 will give great "wood effect" almost like Kodak HIE. Using a 25A gives "NO wood effect" AT ALL.
