Many actions within Photoshop are destructive, which means that when you make an edit, you lose information. That's why using non-destructive Smart Objects is a wise choice. But they do call for a new way of thinking and working. This excerpt walks you through the steps with easy-to-follow visuals and focused tutorials.

If this were anything but a Smart Object, you'd be stuck with this warp. However, since you converted this to a Smart Object first, you can choose Edit>Transform>Warp once again, and you'll see that Photoshop remembered your warp settings. You can choose None from the Warp pop-up menu in the Options Bar to reset the Smart Object or you can just tweak the warp grid if you want.
