No one who understood what we were trying to talk about would claim that a JPG conversion is a reversible process.

Â...but that genius Floyd did.

I've had a look and I cant see where. Could you refer me to the message?

With pleasure.

That wasnâEUR(Tm)t too tough to find: Posted: Mon, 15 Sep 2014 13:44:18 -0500 Message ID: <8738bs2076.fld@barrow.com>

Wherein Floyd stated the following:

âEURoeA non-destructive workflow means you can *undo* and then *redo*.

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.âEUR

Note, the words, âEURoesave it as a JPEG,âEUR.

As I said, that genius Floyd did.

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.
