Re: Sharpening levels

It would depend if you're sharpening for the web, print or publication.

Re: Sharpening levels

Depends if you want to sharpen the whole picture or just various portions of it using layer masks etc. Best to use smart sharpen filter as opposed to unsharp mask. However, I think the best method is to use the High Pass Filter with a radius of 5 to 12 pixels on a duplicate layer then using the opacity slider on the layer it becomes totally variable between 0 to 100 percent. Here is a link that explains the procedure, http://layersmagazine.com/sharpening-high-pass.html

Hope you find it useful

I use smart sharpen for web posting as it's quick and easy.

I use the High Pass Filter for print and publication. For print I sharpen to the degree I need for final output. For publication I under sharpen so the prepress person can sharpen to their requirements.

Re: Sharpening levels

It's hard to be definitive about the amount of sharpening. Raw files usually need more sharpening than JPEGS, depending on how much sharpening has been applied in-camera. AS already mentioned it then depends on the intended use and also on the amount of resizing, if any. If in doubt it's always better to under sharpen rather than over sharpen and for this reason when taking JPEGS I alway have the in-camera sharpening turned right down. More can always be added later but to much to start with cannot be undone.

I use selective sharpening and High Pass Filter ocassionally, when I'm having trouble getting it right by other means, but I must admit to being a bit of a heathen and using the Adjust Sharpness tool in Elements.
