I was saying that I doubt nospam could get his mind around the thought that "A reversible function and ditto workflow ain't the same thing". The evidence is that he (and you) can't.
of course i can.
what you and floyd fail to understand is none of that matters to anyone except you and floyd."Anyone" being only you then. Everyone who has an interest in the OP's questions about sharpening is very interested in the fact that USM is non-reversible.
users are interested in getting the best results with the least amount of hassle. they don't want math tutorials or whether a function has an inverse.Yes, some users want cookie cutter solutions and have no ability to make use of, or understand, the underlying technical details. Unfortunately for you and other like that, becoming expert at most very technical persuits such as photography requires getting past the cookie cutter.
Memorizing all the details in a "Photoshop for Dummies" book won't make you a photographer, and won't help the rest of those who aspire to such who have to read this unending diatribe you produce in this newsgroup.
users edit their images with lightroom (or aperture) and can change anything at any time at any point in the future, *including* altering unsharp mask. to them, *everything* is reversible. that's the *reality*.No, it's just a very narrow view that includes only the simplistic workflow that you've been able to achieve for producing cookies.
Given real world problems, you offer Chocolate Chip cookies in two varieties: with and without the chips.
to put it another way, i can change the amount of unsharp mask on an image i processed a year ago, without having to redo *anything* else i did. all of the retouching, white balance, etc. remain the same (unless i choose to adjust those too).And you can indeed do that with the non-linear undo facility at your disposal. That is a pretty narrow case though, and it is not what "reversible" is all about.
For example, the copy of that image you sent to others, perhaps at a large pixel dimension, cannot be resampled to a lower pixel dimension for printing in a brochure at 3x3 inches because the USM, which was excessive to start with, cannot be reversed. If you had used another form of sharpen for better effect, the copy would have been useable. That is not an insignificant point. They end of rejecting your image, and buy one from a photographer.
