I've been shooting TMax 100 in 120 and 4x5 developed in Tmax developer in my Photo-Therm SSK8R processor. I'm in HOtLanta, GA (Atlanta, GA) and have to process my film at 75 degrees F due to the temp of the water coming out of the tap. My times for Tmax 100 are running 4.5 minutes for 120 film and 4.0 minutes for 4x5 film. I'm shooting Tmax at ASA 100 with these development times and I'm getting a great density curve when I run the density tests on the films. (Densities check on my X-Rite 810). Negatives are scanned on a Howtek 8,000 line drum scanner and worked digitally thereafter.
I'm reasonable pleased with the results BUT I keep hearing good data on the Acros 100 film. In searching and reading a great number of prior posts on the Acros film, I felt that Rodinal was one of the preferred developers. However, I've found that the Rodinal is no longer available and thus will substantially change the value of prior post of that film.
I ask three questions:
1.) Those that have contrasted the Tmax 100 and Acros 100 in both 120 and 4x5 - what did you see as the advantages of each?
2.) What are the attributes of the various developers you have tried with the Acros 100 and what have you standardized on?
3.) Some suggested starting ASA's, rotation rates and development times for the developer that you fondest of with the Acros film?
PS: Emphasis on 120 film as frankly, I'm finding I'm doing far more of my shooting with 120 film these days when I travel by plane to the destination. Just a whole lot easier for me to hike with and I'm doing a lot of panorama shots these days - the H1 and a RRS pan head work great!
