HighPass filter for sharpening

This one doesnt need sound as its quite straight forward... BUT there are a few buts......
As with most things in Photoshop, less is more...... you can always add to it but you can't take it away, so if you have to do this in a couple of passes so be it!!

And as always DO IT ON A LAYER! that way you can blend it in - or delete it if you don't like it and nothing will be lost.

OK to start, duplicate the layer, then goto Filter-Other-highpass. Adjust the radius until the structure starts to show and hit ok. Under the layers tab change the blend mode to either Overlay or Soft light. Blink the layer on and off to see the difference and choose the best one for you. If you have over done it a bit try changing the opacity of the layer to tone it down a bit, or if its complete rubbish, delete that layer and start again!

Its best to watch the vid in fullscreen mode...
