whats your tecnique to sharpen?

I've read a few articles that explain ways of sharpening an image other than using un-sharp mask. things like sharpening the lightness chanel in lab color, or using the high pass filter and then using the overlay blending mode. I was wondering if any of you have used these tecniques or any other tecniques to sharpen your images. and which one works best for you.

  I just use the sharpening tool on my (very basic) software program as the final step after all other enhancements and corrections incurred during the scanning process have been done.

Typically,...around three "notches" of sharpening is all most images can handle without falling apart.
One thing I've noticed is that bright, pin-point highlights on dark surfaces look exaggerated when sharpening is applied so I'll give these only one or two clicks of sharpening.

It's also possible to crop a portion of the frame which can handle more sharpening, a straight horizon. Then, crop the other part of the frame containing pin-point highlights and sharpen that portion less.

  high pass is one of my favorites. it seems to be one of the best unobtrusive methods out there and also when you enlarge a great deal you don't see white lines all around your image from the ugly unsharp mask. I prefer high pass.

  I use unsharp mask on PS. The sharpen tool was actually designed for lithographers and the unsharp tool for phtogaphers. Even though they both sharpen to an extent I think the unsharp "works" the image a little more.

Here's an example of what I mean.

The left side is before and right side is after I used unsharp mask.
