That is not a reversible function.For example, you can add sharpening with a high pass sharpen tool to an image, save it as a JPEG, send it to someone else, and they can use a blur tool to reverse the sharpen.If the sharpening is done with UnsharpMask that cannot be done. USM is not reversible.âEURNote, the words, âEURoesave it as a JPEG,âEUR.As I said, that genius Floyd did.Floyd L. Davidson
So we now we know you can't read.
What I said was that *high pass sharpen is reversible*. It is, even if a few people are unable to either understand or accept that it is.You're ignorant. HPS is *NOT* reversible with gaussian blur if the original image has been compressed as a JPG in between the actions. You know absolutely nothing about images, image data or image processing. Stop trying to fool yourself.
