I'm after some advice about sharpening in Potatoshop, I've tried it in LR1 and didn't like what it did so I'm trying it in PS and still struggling. When I did a basic PS course at college a few years back the advice given was that using the USM filter the amount should never exceed 150, radius should never exceed 1.5 and threashold shoud be below about 5 to have any effect.
I scanned some negatives at 300ppi to make some contact sheets, used the above settings and they looked fine, now I'm doing it on much bigger files those settings don't seem to be having much effect. The original files were about 650px by 650px, the new scans done at 2400ppi are 5000px by 5000.
Does the amount/volume of pixels have an effect on the settings for sharpening and if so how? Can I just use whatever settings appear to have the desired effect on screen or am I at risk of dergading the image?
