Re: [Digital BW] Sharpening/downsizing for web?

2001-10-31 by Julian Thomas

Jerry,
I use GF differently to Robert. I spot and sharpen using Ultra Sharpen 3 and
then save as an .stn file. If I'm scanning 1600dpi 6x6 neg, that is what I
save as. from this, say i want a 7inch sq print. I type in 490dpi in the
output size box. GF automatically resizes the print and then I get my 7inch
print. I may be doing this wrong, but I can't see the difference from doing
it the other way. I've tried it - but can't see it.
