UnSharpMask is not reversible.

it is with a non-destructive workflow.

I'm sorry that you don't understand the meaning of that.

I know your feelings regarding Photoshop, but using Adobe's *Smart Object* concept provides a different level of non-destructive workflow. Creating a new adjustment layer and converting it to a *Smart Object* gives one the ability to apply any filter, including USM and any of the other sharpening tools or filters to that *Smart Object*. If the particular adjustment results are not to one's liking, then double clicking on that filter in the *Smart Object* layer will reopen the filter dialog to allow changes to the filter parameters. In the case shown below I have applied USM to a *Smart Object* and I can return to it as often as I want to adjust the USM parameters, all non-destructively. <https://dl.dropbox.com/u/1295663/FileChute/screenshot_900.jpg>

All adjustments made to *Smart Objects*, in Photoshop terms, are non-destructive.

true, but i was thinking of lightroom where no additional steps are required because everything is non-destructive.

with photoshop, the user has to take additional steps to be non-destructive.

I fully expect you to tell me I am wrong.

of course.
