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

2001-10-31 by Jerry Olson

Robert, 

How do you use genuine fractals if you know you will be making many
different sized prints? Can't you just make one master file, save it,
and print it at any size? 

If not, what is the proper order to sharpen files that you know will be
printed at sizes from 5 inches wide to 24 inches wide, and many sizes inbetween?

Thanks,

Jerry

My Genuine Fractals program will be here in a today, so am curious as
how this works.
