With snapshots, you can recover your work easily. When you experiment with a complex technique or apply an
action, take a snapshot first. If you’re not satisfied with the results, you can select the snapshot to undo all the steps.
Note: Snapshots are not saved with the image—closing an image deletes its snapshots. Also, unless you select the Allow
Non-Linear History option, selecting a snapshot and changing the image deletes all of the states currently listed in the
History panel.

Paint with a state or snapshot of an image
The History Brush tool
lets you paint a copy of one image state or snapshot into the current image window. This
tool makes a copy, or sample, of the image and then paints with it.
For example, you might make a snapshot of a change you made with a painting tool or filter (with the Full Document
option selected when you create the snapshot). After undoing the change to the image, you could use the History Brush
tool to apply the change selectively to areas of the image. Unless you select a merged snapshot, the History Brush tool
paints from a layer in the selected state to the same layer in another state.
