Or you could just shoot Tri-X.   Isn't this an awful lot of work to make 
one's way back to what film has been doing for generations?   I don't mean to 
reignite the old film/digital debate; there's no sense in arguing which is better; 
they each have their strengths; they are different tools.   But it does seem 
perverse that people embrace a new technology to mimic the appearance of an 
old one.
