Retouching and transforming

Note: If a selection exists, the filter limits the preview and processing to the rectangular area containing that selection.
(For rectangular marquee selections, the selected area and preview are identical, so choosing Selection from the pop-up
menus above has no effect.)
Thaw areas
❖ Do any of the following:
• Select the Thaw Mask tool , and drag over the area. Shift-click to thaw in a straight line between the current
point and the previously clicked point.
• To thaw all frozen areas, click the None button in the Mask Options area of the dialog box.
• To invert frozen and thawed areas, click Invert All in the Mask Options area of the dialog box.
Reconstruct distortions
After you distort the preview image, you can use a variety of controls and reconstruction modes to reverse changes or
redo the changes in new ways. Reconstructions can be applied two ways. You can apply a reconstruction to the entire
image, smoothing out the distortion in unfrozen areas, or you can use the reconstruction tool to reconstruct specific
areas. If you want to prevent reconstruction of distorted areas, you can use the Freeze Mask tool.
Reconstruction based on distortions in frozen areas.

Reconstruct an entire image
1 Select a reconstruction mode from the Reconstruct Options area of the dialog box.
2 Press the Reconstruct button in the Reconstruction Options area to apply the effect once. You can apply the
reconstruction more than once to create a less distorted appearance.
Remove all distortions
❖ Click the Restore All button in the Reconstruct Option area of the dialog box. This removes distortions even in
frozen areas.
