Making a snapshot of the 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 the snapshot lets you work from that
version of the image.
Important: Snapshots are not saved with the
image—closing an image removes all 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.
Snapshots let you do the following:
Switch repeatedly between several states. By
•
taking a temporary snapshot of a state, you can
keep that state for the entire work session, even if
the original state is deleted from the list of states in
the History palette.
Give a unique name to states, to make them
•
easier to identify.
Experiment more freely. For example, you may
•
want to compare two different techniques for
achieving a similar effect. You can take a snapshot
before and after trying the first technique. You can
then select the first snapshot, try the second
technique on it, and then compare snapshots of
each technique.
Take a snapshot before creating or applying an
•
action. Then you can recover your work more
easily if you decide later you don't like the action.
Each step in an action is added to the list of states
on the History palette. An action with many steps
could scroll the current states off the palette, so
that you could not return to any of them. Using the
Undo command undoes only one step and state.
By making a snapshot first, you can select and
redisplay the pre-action image.
To create a snapshot:
1 Select a state.
2 Click the New Snapshot button ( ) on the
History palette, or choose New Snapshot from the
History palette pop-up menu.
3 Enter the name of the Snapshot in the Name
text box.
4 For From, select the snapshot contents:
Full Document to make a snapshot of all layers
•
in the image at that state.
Merged Layers to make a snapshot that merges
•
all layers in the image at that state.
Current Layer to make a snapshot of only the
•
currently selected layer at that state.
Click OK.
5
To select a snapshot:

•
Drag the slider at the left of the snapshot up or
•
down to a different snapshot.
To delete a snapshot:
Do one of the following:
Select the snapshot, and choose Delete from the
•
pop-up menu on the palette.
