PK Sharpner question

[sniper]

As one of the many on this forum who use PKS for my sharpening (on the recomendation of some here) I got courious about how it actually works, as it's working within PS and is a script??  am I right in assuming it has to use the native filters etc in photoshop?
 I know it uses a complicated system with layers etc but could you achieve exactly the same without it just using photoshop?   Wayne

Here's a link to an old essay of Michael's on PKS that may be helpful and explain more.

My link to Bruce Fraser's workflow, etc. for sharpening doesn't work any longer--but I thought I saw Andrew Rodney link to it--or another page that is similar (which is what PKS is based on) so perhaps he or Jeff Schewe will step in here and give you more info.  I have used it for a number of years and find it far superior to anything else I've tried--but you could use Bruce's approach (I did find a link after all).

Read the above in the opposite order--I pasted in the links in the wrong order.

This one may be helpful too--but its sure a lot easier to use PKS LOL.

I think that you could achieve the same effect in Photoshop if you knew the numbers to plug into the various filters and sliders, but that would require quite a bit of research and testing. However, a roll your own approach could use other sharpening algorithms, such as the newer deconvoluiton methods. You could also insert third party noise reduction filters when needed. Since sharpening and noise reduction are antagonistic processes, it would be nice to incorporate both processes into the same tool.

If interested, you might find Bruce Fraser's [a href=\"http://www.amazon.com/World-Image-Sharpening-Adobe-Photoshop/dp/0321449916]Real World Image Sharpening[/url] book useful. It basically show HOW the processing steps are created (but doesn't give you the "magic numbers" actually used in PhotoKit Sharpener).

But, more importantly, it does explain why you need to do sharpening...

Thanks guys, theres some interesting info there.  Jeff I'll have a look for Bruces book, although I'll probably have to order it online as any decent books are hard to get around here.  Thanks  Wayne
