Jay:

I developed a negative tonight in 510 at 1:200 using a semi-stand regimen. 4 periods of 10 minutes each at 72 degrees F. Gorgeous. Image stain out the wazoo and very clean. It looks a little thin, but then again so do some of Steve's and there is beau coups stain so it may print with a surprising amount of contrast. I have another one to do tomorrow night and then I'll proof them both on Sunday. Stay tuned. It looks like 40 minutes or so is the time for a normal TMax negative (SBR 7).
