shot 10 rolls of 120 3200 delta last week. Tested at 800,1250,1600,3200,6400,12.5k and 25.k in tmax RS. 800 to 1250 is close to the actual speed I devleoped it in tmax rs 1:1 for 6 minutes @ 75f. Looks like tri-x! The film does very well up to 6400 but I recommend not diluting above that point. You may fall asleep during the developer cycle! I can't wait until someone finds me a combo for 3200 delta pushed to 12.5k and 25.k heee.... or I cling to the hope that DDX works better than tmax rs for the push!(posted 9195 days ago)
