Re: More on lpm in print (TECH-3D digest 2)

RE: John Ohrt remarks on needing 160 lpm in neg for a 20x 
print. This computes to 8 lpm in print, BUT I think the 7-8lpm is for 
reading distance and small prints up to letter size. IF viewing is 
properly at twice the diagonal of a print (i.e. no grain sniffers), 
then I don't think the 7 lpm is still needed, although I can't see 
how it can get much smaller. e.g. from across the room maybe its 
lines per inch now! :-) BobH
