Ok folks I made a tutorial on how I sharpen images with my 3 step edge mask sharpening this is for Photoshop CS3 if you have an eariler version you will need to use layers instead of the smart objects.
I will also explain what i mean by the 16.67%,33,3% and the 66.67 are bad sizes to work with will editing an image not the end result as I feel some of you are confused with but while doing your edits ok.
The action that I wrote named sharpen for effect.atn is availible at the same down load site it does what I have done in this tutorial so you can use the action or you can do each step as I have explained and why I did each step in the video
here is The Link http://thekiwi.org/Dave/ I ask that you forgive the coughs and the splatters on the video as I haven't been to well of late and I hope you all can understand basic Kiwi
Sorry the file is quite large it is approx 36MB
good luck hope it works for you
