Photo Tool, some misunderstand perhaps?

[jclements]

From reading some of the postings, I was under the impression the effects applied to the photo using the Photo Tool could be UNDONE one-by-one, similar to what can be done with the plugins and the photo editor.

I only found the Compare button in the Info Bar which undoes ALL applied effects.

Please enlighten me if I am over looking something.

'Compare' is designed to allow you to look at the original un edited version of the photo you have selected, it is not an undo feature. Pressing 'Compare' a second time brings you back to your edited version with all edits in place.
Ctrl+Z steps back and removes your edits one-by-one as normal.

Once you save and close the file though, you loose your undo's so it all or none (compare and return to the original photo or toggle back to the last photo change), correct?

[steve.ledger]

Correct - undo buffers are not saved, which is industry standard.

But keep in mind that the settings to contrast/levels/etc/etc don't actually modify the underlying image, so you can still turn those off later on even after a save/reload and get back to your original image. What you lose is the ability to selectively turn each change off in the reverse of the order that you made them.

Absolutely.. And is why it is important to also save your work as a .xar file rather than simply exporting to bitmap and then closing.
