We are descending into silliness here. A reversible process is one where any changes made in the execution of that process can be reversed to revert to the original state.

A non-destructive work flow does not make a process reversible.

All it does is let you have another go at a process using different settings.

Then why are you rabitting on about non-destructive work flows?

Savageduck
Because there is more to this thread, and NG than the arcane pontificating of Floyd D, and more over he, or anybody else here doesn't control the flow and drift of any thread.

Eric Stevens
Floyd was trying to address the question raised by the OP. The arrival of nospam and then you on the scene confusing non-destructive editing with whether a process is reversible or not has brought all sensible discussion to a halt.

Savageduck
There is much more to post processing than Floyd's way of doing things. Even though he denies the reality of the tools available to the Photoshop user.

Eric Stevens
I'm afraid it's not a turf war. What Floyd said was perfectly correct and fundamental.
