Hi, when I open the optimized sharpening tool and apply some sharpening, I get a very crispy effect in the preview, but after applying it to my picture and the tool window closes, the effect disapeares and my picture looses that crispy effect (sometimes for the best, but, still...), which I don't quite understand. Can someone explain ? It is supposed to visually guide us about how much sharpening we want to apply...

Anything less than 100% has to combine several image pixels into each screen pixel. Also any image viewed at less than 66.7% is composited using 8 bit previews of each layer - not the full layer data, even when that layer data is 16 bits/channel. Always check sharpening and compositing at 100% zoom

Are you viewing the preview and your final with your image both at 100%. You can't guage how an image actually looks, unless you're at 100%

Hi Chuck,

I usually use either 25% or 50 % as I was told they are "viewing steps" where you can see the real effect of sharpening, so You're saying only 100 % gives me the real thing ?
