Advanced Sharpening Techniques

[Dirty_Ass]

I was wondering if you guys had any super-secret sharpening techniques that you use, or any good tutorials on getting super-sharp shots. Thanks

unsharp mask is generally the most professional sharpening tool

Sharpening just the luminance channel with the high pass filter works well for me.

That's a great method, and one I use. Also, you can sharpen individual channels. Sometimes this can be helpfull, since more often than not Blue and Green have the most contrast. But, you can also run into trouble sharpening either of them becuase you will also make the noise more pronounced as well, and they usually how most of the noise.

The Unsharp mask is great, but it's values are dependent on the resolution you are working. A 2 pixel with a value of 75 is going to sharpen more at 72 dpi than 300.

And if all else fails, draw the detail back in. :thumbup:

Also, Photozoom pro has some pretty cool S-spline sharpening techniques.
