I am a big fan of the Delta films. Delta 100 is a wonderful film, but I generally use Delta 400 (new version). Both have excellent sharpness, acutance, contrast and tonal range (depending, of course, on how it is used and developed). Maybe not as much latitude as HP, but finer grained. As for DDX, I have used it with good results on the new Delta 400. Also worth trying Xtol and ID-11.(posted 8528 days ago)
