I've recently been experimenting with pushing two 400 speed films to 1600: Kodak's TMax and Ilford's Delta. The developing times for each, with stock Xtol at 68d egrees F, are 8.5 minutes for the Kodak and 13 minutes for the Ilford. These are manufacturer published times. However. While the Delta 400 negatives are nice, with good shadow detail, and good exposure, the Kodak negs are horrible. NO shadow detail and all the negatives look devoid of detail outside the best-lit areas. Is that what's supposed to happen? Is Kodak off its rocker here?
