Using Image Enhancement History
To commit or undo your image edits (one by one or all the steps),
use the History panel in the Image Enhancement window. Once you
have modified the original image, its preview displays the changes,
3D Deskew works by snapping the distorted image to a grid. All
you need to
do is to manually straighten this grid, and image
coordinates will follow - see illustration below (before - after 3D
Deskew).
