John, do you ever make 30x enlargement out of your large format negative? I wonder if the biggest you make is something like 4x or 6x then why bother? If that resolution goes away when you stop down to f/11 or f/16, then again, why bother? So far, only the advantage I can think of of Acros is less departure from the reciprocity law. You also mentioned increasing contrast in highlight areas, which may or may not be advantageous.(posted 8176 days ago)Off topic: for 120 size HP5+, Delta 400 and TMY have negligible price difference. However, in 35mm (36exp) the price for Delta 400 is almost double that of TMY (international packaging). Do you think it's really worth it? (Or is it just a matter of finding the right developer for TMY??)
PS. I think I found a PostScript file to print a resolution test target chart somewhere before. I have my copy (file and printed one on my wall) but I can't remember where I got it from...
