A powerful tool in Photoshop's formidable arsenal of restoration and correction tools is the Spot Healing Brush With a name similar to the Healing Brush, you might expect that the tools have similar features, and you would be correct The main difference between the two tools

is that the Spot Healing Brush does not require you to take a sample of the area to heal The Spot Healing Brush tool takes the area sample as you work by sampling the surrounding pixels The Spot Healing Brush,

as its name implies, works best on small spots and imperfections To heal larger areas, the standard Healing Brush, Patch tool, and even the good old Clone Stamp tool are your best bets

The Spot Healing Brush smoothed out some of the wrinkles

The Red Eye tool not only gives the digital restorer an excellent tool for removing pesky red eye, it will also remove the green and white reflec-tions in pet's eyes The biggest generator of red eye is the onboard flash on your camera Actually, if they would simply rename a camera's built-in flash, "red eye generator," it might help amateur photographers pay more attention However, until that day comes, designers will still have to deal with images that contain red eye The Red Eye tool per-forms two operations: it desaturates the red values, and darkens the pupil

The red eye is removed with the click of your mouse.

The Levels adjustment lets you adjust the tonal range of an image by giving you three sliders—one for shadows, midtones, and highlights

Dragging the sliders precisely adjusts the tonal ranges of an image In addition, the Output sliders let you adjust the ink percentages used to print during output By adjusting the output ink levels, you avoid the overly black images that sometimes plague images printed with high dot-gain papers
