thank you Bill for your report. my initial comparisons with new Delta 400 versus TMY is that TMY in Xtol has finer grain than the Ilford offering. Delta 400 in Xtol is quite beautiful, on par with TMY in my estimation though with increased grain. my main objection to this film and Delta films in general, is the base material. whereas TMX and TMY have a thicker base and lie flat on the light table and scanner bed, Ilford films curl radically.(posted 8537 days ago)another note, TMY and Xtol yields finer grain that Delta 400 in Perceptol. like you, I have found a dynamic duo (when it behaves) and find myself heavily invested and committed to TMax films. this is 120, whereas in 35mm and 4x5 I prefer the Ilford films.
glad you found success .. enjoy it.
