Select the area you want to restore, and choose Edit > Fill. For Use, choose History,

Note: To restore the image with a snapshot of the initial state of the document, choose
History Options from the Palette menu and make sure that the Automatically Create First
Snapshot option is on.
Reverting to a previous version of an image
The History palette lets you jump to any recent state of the image created during the
current working session. Each time you apply a change to an image, the new state of that
image is added to the palette.
For example, if you select, paint, and rotate part of an image, each of those states is listed
separately in the palette. You can then select any of the states, and the image will revert to
how it looked when that change was first applied. You can then work from that state.
About the History palette
Note the following guidelines when using the History palette:
Program-wide changes, such as changes to palettes, color settings, actions, and prefer-
•
ences, are not changes to a particular image and so are not added to the History
palette.
By default, the History palette lists the previous 20 states. Older states are automatically
•
deleted to free more memory for Photoshop. To keep a particular state throughout
your work session, make a snapshot of the state. For more information, see
snapshot of an image (Photoshop)" on page
Once you close and reopen the document, all states and snapshots from the last
•
working session are cleared from the palette.
By default, a snapshot of the initial state of the document is displayed at the top of the
•
palette.
States are added from the top down. That is, the oldest state is at the top of the list,
•
the most recent one at the bottom.
Each state is listed with the name of the tool or command used to change the image.
•
By default, selecting a state dims those below. This way you can easily see which
•
changes will be discarded if you continue working from the selected state. For infor-
mation on customizing the history options, see
on page 40.
By default, selecting a state and then changing the image eliminates all states that
•
come after.
If you select a state and then change the image, eliminating the states that came after,
•
you can use the Undo command to undo the last change and restore the eliminated
states.
By default, deleting a state deletes that state and those that came after it. If you choose
•
the Allow Non-Linear History option, deleting a state deletes just that state. For more
information, see "Setting history options (Photoshop)" on page
