What I typically do is back into the ISO rating based on the volume of light and the minimum shutter speed that is needed for the subject. The lense that I use determines the slowest shutter speed that I can get by with. If I am using a lense with a focal length less that 50mm I can typically hand hold the camera at 60th second or less. If it is a longer focal length I will not risk a shutter speed less than 125th. Therefore, in all of my shoots the lighting has been adequate to use a lower ISO rating. The formula that I typically use that works for me is to set the ISO at 80% of the manufacturers suggested rating and process at 10 to 20% less than the recommended times. I use Xtol exclusively therefore, if I were using this film I would set the ISO at around 2600 and process in Xtol stock solution at 68 degrees for 5 minutes and 55 seconds. This is a starter time but I think you would be in the ballpark. Depending on how you agitate and temperature accuracy adjustments to this time may be indicated. This is a beautiful film and regardless of the ISO you settle on you will be pleased with the result. Unlike TMax it is very forgiving. It is the opinion of Erwin Puts and Nathan Wajsman that the film works best in the ISO 1200 to 1600 rating. I have shot about a dozen rolls of this film and I concur with their findings. Best of luck and please let me know how it works for you. Bob Bedwell << Bob Any thoughts as to developer combos to use with Delta 3200 shot at EI3200? Ernie >>
