To delete all of an image’s states (ImageReady):
Choose Clear Undo/Redo History from the History palette menu.
Important:
This action cannot be undone.
To create a new document from the selected state or snapshot of the image
(Photoshop):
Do one of the following:
•
Drag a state or snapshot onto the New Document button
.
•
Select a state or snapshot, and click the New Document button.
•
Select a state or snapshot, and choose New Document from the History palette menu.
The history list for the newly created document will be empty.
To save one or more snapshots or image states for use in a later editing session, create
a new file for each state you save, and save each in a separate file. When you reopen
your original file, plan to open the other saved files also. You can drag each file’s initial
snapshot to the original image and thus access the snapshots again from the original
image’s History palette.
To replace an existing document with a selected state (Photoshop):
Drag the state onto the document.
Setting history options (Photoshop)
You can specify the maximum number of items to include in the History palette and set
other options that customize the way you work with the palette.
To set history options:
1
Choose History Options from the History palette menu.
2
Select an option:
•
Automatically Create First Snapshot to automatically create a snapshot of the initial
state of the image when the document is opened.
•
Automatically Create New Snapshot When Saving to generate a snapshot every time
you save.
•
Allow Non-Linear History to make changes to a selected state without deleting the
states that come after. Normally, when you select a state and change the image, all
states that come after the selected one are deleted. This enables the History palette to
display a list of the editing steps in the order you made them. By recording states in a
nonlinear way, you can select a state, make a change to the image, and delete just that
state. The change will be appended at the end of the list.
•
Show New Snapshot Dialog By Default to force Photoshop to prompt you for snapshot
names even when using the buttons on the palette.
Making a snapshot of an image (Photoshop)
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.
