Ive been watching this site for over a year and I'd just like to say that I appreciate what you guys do very much! I have been shooting 4x5 and contact printing for about 16months now (i dont have access to a darkroom and cant afford an enlarger). I have been using tmax100 film and tmaxrs developer in a jobo cpp2 that was given to me by a friend who no longer shoots. I have been looking to switch to Pyrocat-HD, but I have no experience with any film but tmax100. I would really love to try Efke 100, and was wondering how well the film would work with pyrocat-HD.. Also, what is a good starting point with the combination in terms of temperature/development times ?
