You can choose to have red eye effects corrected automatically during the import process—simply activate the Automatically Fix Red Eye option in the Import dialog box. To fix red eye after the photos have been imported, choose Edit > Auto Red Eye Fix in the Organizer. In either the Full Edit or Quick Fix mode of the Editor, choose Enhance > Auto Red Eye Fix. Alternatively, you can fine-tune the Red Eye Removal tool from the toolbox if you need more control.
Use the Undo History palette to quickly undo a series of steps at once. Every action performed on the file is recorded in chronological order in the Undo History palette. To restore the file to an earlier state, simply select an earlier action—higher in the list—in the Undo History palette. If you change your mind before making any further changes to the file, you can still restore the image to a later state by selecting a step lower in the list.
Both the Healing Brush tool and the Spot Healing Brush tool blend pixels from one part of an image into another. The Spot Healing Brush tool, especially with the Proximity Match option selected, enables you to remove blemishes more quickly than does the Healing Brush, because it only involves clicking and/or dragging on an imperfection to smooth it. The Healing Brush can be customized, and requires that you Alt-click to establish a source reference area.
The Dust & Scratches filter smooths out pixels in an image by blurring them slightly, effectively putting detail slightly out of focus. It was necessary to create a selection so that only the background was blurred, preserving sharpness and detail in the subjects.
A mask is simply the opposite of a selection. A selection is an active area to which adjustments can be applied; everything outside the selection is unaffected by any changes that are made. A mask protects an area from changes. Another difference between a mask and a selection is the way Photoshop Elements presents them visually. A selection marquee is indicated by a flashing border of black and white dashes, whereas a mask appears as a colored, semi-transparent overlay on the image. You can change the color and opacity of the mask overlay using the Overlay Color options that appear in the tool options bar when the Selection Brush tool is set to operate in Mask mode.
