Technically spoken, XTOL is a fine grain developer, and a mediocre acutance developer. You can change things by adding dilution, grain will increase (a little bit) but acutance will get A LOT better. I have had the shapest results on XTOL 1:3 with Delta 100. Even with higher dilutions might be expermented with, for low contrast and compensating development on document films as Tech Pan. Also a little bit increase of real speed will be observed, and last but not least it's very economical !(posted 8431 days ago)
