Hi Bruce?.. Remember the Ft. Worth Workshop with Les McLane? #1, the times for the old and the new are SLIGHTLY different?. I use TMAX RS developer, so I have no first hand specific info. I went looking at J78 to be sure?..yes, ,you are correct?.. straight, no dilution for 9 ½ minutes ???J78 Dated 2002 Then I looked at F4016 and yes, you are correct again? no dilution is stated??for 6 ¼ minutes? F4016 Dated 2004 I would start with the newer data?? I think I remember there was an issue with development times with TMAX when it first came out and the first data may never have been updated??.

The Kodak bulletins are confusing as to "New" versus "Old" T-Max and I'm supposing I will receive "New", the PROFESSIONAL T-MAX 100, rather than the "Old" T-MAX 100 PROFESSIONAL. But their published suggested times are more confusing. One bulletin (J 78) says T-Max 100 Pro rotary processing for D 76 1:1 is 12 minutes at 68F and Pro T-Max 100 rotary processing in D 76 1:1 is 9 1/2 minutes while another bulletin (F-4016) says it is 6 1/4 minutes but it does not indicate a dilution or if it is stock solution. These are big differences, can you suggest a starting time? Bruce Osgood Camclicker @ aol.com Brooklyn, NY. _____ Who's never won?
