Are edits made with iPhoto and Aperture permanent?

When using Photoshop, you should always clone and lock your layers. Clone and lock your first layer and then each layer after you save. Turn them invisible so you can see the current layer you are working on. Also when you begin a project, make sure your history is set to show the last 50–100 edits done so you can easily go back if you don’t like a change you’ve made.

If you don’t clone your layers or have your history set to 50 or more, I’m sorry but your changes might be permanent. =[ It took a while for me to get used to it. You can’t just click undo because it will only undo your last edit.

Sorry, I misread this question. Haha, whoops. But no! Edits made with iPhoto are not permanent! when you go back into edit it will show the full photo (if you cropped it) and you can undo just about anything, I believe. But it will not show a list of your previous edits like Photoshop does.

With iPhoto find the iPhoto library in your pictures folder. Right click it and select Show Package Contents.

The originals are in the Masters folder. The result of your edit is in the Previews folder.
