It could be my meters. I noticed with TMY first came out that it was a full stop slower under tungsten light than daylight, at least for me. Kodak's response curves do NOT bear this out, but it's the result I get, and across a range of several meters (at least two 35mm Pentax with built in metering and my Soligor spot meter for 4x5.) To be fair I don't recall making the comparison with my Luna Pro SBC or with my Mamiya 645 AE prism.
Still, the results I got originally with TMY were with the same meters that worked fine in that light with the Tri-X of those days. I can't explain it, I just know what I have to do to get good results with my equipment and methods.

I haven't updated (or had time to print) in a long time, I'm afraid. Life has been happening, in most annoying and time-absorbing ways, but I expect that to change soon.
