New Techniques Page: Guide to Image Sharpening

[McQ]

Excuse me Sean if I am wrong but I would like to know if your statement
"Sharpening is irreversible; also save unsharpened originals whenever possible."

Thanks for the feedback. Yes, smart objects are a nice workaround, but technically speaking, sharpening is never really applied to the original image when using a smart object (except in on-screen previews or converting the file to a non-PSD file format). Think of smart objects as files which include a set of instructions that are attached to the original image data and followed when needed, but that never actually modify this data. Unfortunately, sharpening is currently still an irreversible process when it is applied to the image data itself.

At the Bottom of the page:

The light sharpening halos are often more objectionable than the dark ones; advanced sharpening techniques sometimes get away woth more aggressive sharpening by reducing the prominence of the former.

It is pretty minor but just thought I would point it out
