Differences in sharpening techniques

[bfcoughlin]

There are different ways to sharpen an image. Can anyone tell me the differences between Unsharp Mask and the technique that uses the High Pass filter with blending modes? What are the pros and cons of each? Are there particular circumstances that would call for one over the other?

Thanks!

Hi BF,

I'm no expert on sharpening, but I can point you to a couple of sites that were linked in previous threads here. These articles contains some pretty good reading.
