Response to Sharpness

from shawn (shawngibson_prophoto@yahoo.com)
Yeah, from a common sense place, t-grained films should be sharper, and from what I have seen (only a few years experience, remember...) they are sharper in one sense, but they appear less sharp than some traditional combos to the eye. I'm willing to be nailed as wrong here, but I have only gotten very sharp (to my eye) TMY negs once, and they were WAY sharper than anything old tech.

One thing I'd like to touch on is another question: how come no other emulsions have even come close to matching the resolving power of Technical Pan? There is more than double the resolution with TP over some of the highest-tech films in use today? And how does resolution relate to acutance? I'm sure they are related deeply, if my prints tell anything...

Charlie: with PMK, I use a 2-3sec every 15 sec. agitation cycle...would my images be sharper switching to 20sec? Why? Does it have something to do with infectious development or one of those other slightly esoteric problems?
