Confused? Well, it’s much simpler than the title of this entry. Google+ Photos is giving users the ability to return to the previous edits you’ve done on your photos. It also keeps the original image intact so you don’t have to worry about your image getting “destroyed.” For example, you can keep the frame choice you selected for a previously edited image and adjust brightness and contrast. You just need to open “Edits” on the Chrome editor to adjust the edits you have previously made.
According to Engadget, it currently only works on Chrome. But iOS, Android, and Chrome will be getting the new Auto Awesome Effects that stylizes your image when you upload it. Of course, you can remove this edit, too, if you don’t like it.
