I say amount %250, radius 1 and threshold 3

Depends... what are the applications of the image (print, web, etc)? And how big is the image?
 08/16/2006 08:19:07 PM · #3
for prints up to 24x30 or more
 08/16/2006 08:21:47 PM · #4
Your numbers are a good starting point then.

thanks, do you bother with the bicubic smoother in photoshop?
I heard it makes a difference.

Yes, if I upsize an image I use bicubic smoother. Also, I've been using smart sharpen (CS2) more often than USM for sharpening.

For sharpening for print with Smart Sharpen, I like to view the image at 50% and sharpen to taste. Usually starting at about 125% .8 radius.

It also makes a difference for downsizing too. I've noticed a marked difference when using it on images that contain things like blades of grass, whiskers and the like. Without using it those things tend to pixelize.

.... though Bicubic Sharper is the suggested algorithm for downsizing.

Shouldn't you usually wait to sharpen things until you're working with the final size image? Ddepending on heaviness of process of course, but for most lightly or "natural" looking prints, I usually try to save sharpening for the final step.

cpanaioti, you're probably right but I haven't really found much of a difference between those two and tend to go with smoother just by default.
