No, I have no way of measuring dmax... my evaluation is two prints side-by-side propped up on a piece of furniture in the living room... very low tech!

Several weeks passed between my first cataract removal and the second. I would close one eye, then the other, and the difference was incredible. Not only blacks and whites but all the colors were much more vivid. A highly recommended procedure for all old photographers!

I asked Mark what happens when my test reaches 100, and said he's going to continue testing. Well, it's my sample but your procedure! I'm glad that Mark referenced you in his notes on my test... did you notice that? 

Oh, and on another issue I've raised here... the National Register guidelines. An architect I work with got an e-mail from them saying they now prefer color submissions - go figure!
