Feedback for my whilte paper on Sharpening

[freixas]

Hi! There are a lot of clever people on this forum and I wondered if I could get some feedback from you about the white paper I just wrote on sharpening.

The official title is "Sharpening in Photoshop CS4". It includes a fair bit of math and the results of a lot of testing. I would have liked to have decoded the Smart Sharpen algorithms, but after some weeks of research, I just made it through the USM.

I'm particularly interested in any errors I might have made in any of my math or my testing.

Thanks for your time!

I read through it, skipped some of the math, but it certainly clarified some things for me. I am in no position to critique it on a technical level, but I appreciate someone looking into how a function works... it makes it much more intuitive to use a feature when you understand whats going on in the background.

Thanks

Ps- You should look into Smart Sharpen next
