I recently came across the technique to create a new layer, do a high pass at around 1 pixel or so (i've gone as high as 8 or 9 pixels too) and then overlay that with the original layer to get more sharpening. 

Just wondering what you guys use (for those with crappy lens kits like me .  I have been using both but the high-pass tends not to bring out noise as much.

Any comments?
