With regard to Xtol, when I was gathering data from my curves testing, I
thought I had made a mistake along the way, so I repeated the process with
this developer. I got the same results after a second try. A significant
density build or hump starting in the lower midtone. I called Silvia
Zawadski (sp) and Dick, can't remember his last name. They developed Xtol
for Kodak and are now consultants to Kodak as well as others. They explained
the hump as a result of greater activity of the developer on film in the
midtone area. While the explanation was arcane and incomplete, they did own
up to it. I did think from their explanation that the "hump" was specific to
the developer and not the film. I've never seen it with any other
film/developer combo.
By the way, I scanned a bunch of the test film and was pleasantly surprised
to find Tmax 400 the hands down winner so far. I shot test rolls of Tmax
400, Tmax 100, Fp4, PlusX and Delta 400. The subject was a woman from
England. She has very pale, translucent skin with blond hair. She was
wearing a black rayon pullover with tight weave and pants with a loud
grey/white texture. Studio strobe lighting with a polaroid exposure at F11
on a RZ67. The main light was a Desisti fresnel strobe which was bare and
pointed directly at her face from slightly camera right. Very hot light.
Bracketed all film around the indicated exposure and developed in Tmas
developer at 68 degrees using using Anchell's times. The Tmax 400 carries so
much workable tone it was wonderful. This is my first experience with both
the film and developer. I want to try D76 and others. I'm looking for even
greater highlight separation. Any suggestions? If any one wants to see the
results, send your email address and I will forward the scan.
