One gang of people like to produce digital negatives as intermediates in alternative processes. They then obsess about the UV blocking power of the inks for different processes and bang on about log D values for each different process.

All of which is a long way of saying that despite an expensive physics and chemistry education I have some mental blank about curves and thus have problems every time I walk up to PhotoShop. I make my 8x10 negatives in a dev tray but the above kinds of discussion make me wonder about whether I should be exposing differently, developing differently for different AP's.

1) wanted a boy's and girl's first book of densitometry
2) experience of messing with exposing/developing for different AP -- I'd like to start with salt print
