Previewing changes to images
You can use the Preview bar with some editing tools to see how the current editing tool affects a
specific area of your image. You can pan either image in the Preview bar by dragging it within its pane,
and drag the edges or corners of the Preview bar to resize it.
To open the Preview bar:
1 On the Edit Panel, open an editing tool.
2 On the tool panel, click the Preview Bar button.
The Preview bar displays the original version of your image in the top pane, and the edited version of
your image in the bottom pane, with a toolbar between the two.
