I got what Floyd was talking about when he was talking of high pass sharpening, and reversing it by applying the corresponding reverse parameter blur. However, he also stated above, "UnSharpMask is not reversible". My point addressed the fact that for some of us, that is not an entirely valid statement.
That is in fact a valid statement. The USM function is not reversible.
That isn't a opinion, it's a fact.
