Make a snapshot of an image
The Snapshot command lets you make a temporary copy (or snapshot) of any state of the image. The new snapshot
is added to the list of snapshots at the top of the History palette. Selecting a snapshot lets you work from that version
of the image.
Snapshots are similar to the states listed in the History palette, but they offer additional advantages:
• You can name a snapshot to make it easy to identify.
• Snapshots can be stored for an entire work session.
• You can compare effects easily. For example, you can take a snapshot before and after applying a filter. Then select
the first snapshot, and try the same filter with different settings. Switch between the snapshots to find the settings
you like best.
• 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 palette.
