I think the biggest trap people fall into with sharpening is to overdo it..

You will need how to use the unsharp mask filter (search for tutorials on that): but be very cautious with any advice suggesting you use a radius setting of more than, say, 0.5. Sometimes you see the suggestion of amount 100, radius 1.0 (say) as a default procedure, which I find wildly overcooks things. Amount 10/radius 50 is OK, but that's a different technique which is local contrast enhancement rather than sharpening as most people would understand it.tim..

You've overcooked the sharpening a bit and you can see that edges have an unnatural look to them. By far the best guide to sharpening that I've found is here:.

Http://www.cambridgeincolour.com/tutorials/unsharp-mask.htm.

Do read the rest of the tutorials on that site as it's jam-packed with really useful and well-presented information..

I agree..

Well, it really depends on the photo. I would be wary on any hard and fast advice on the settings. Sometimes a radius of 1 or more is best depending on the photo..

Here is a good article on sharpening:http://ronbigelow.com/articles/sharpen1/sharpen1.html.

Note that page 2 of this article goes into detail about the effects of different settings..

Amount 10/radius 50is OK, but that's a different technique which is local contrastenhancement rather than sharpening as most people would understand it..

Again, the settings to increase local contrast vary depending on the image size and other factors...

Another reason why many people oversharpen is due to the output of the photo. You don't require the same sharpening for a web viewed jpg as you would for a printed photo. Many sharpening tutorials are written with sharpening for creating a photo - anyone reading these and using those settings for a web viewed jpg will get crapppy results...

Take a look at this thread on sharpening:.

It's a bit advanced, but may give you good results...
