Redeye

Use to correct red-eye. This implemention requires more manual intervention than most, but the results are fairly pleasing. For each pixel, the algorithm first checks to see if the red value is at least 1.5 times the average of the green and blue values. If so, it then replaces the red value with the average of the green and blue values. This transform helps to preserve highlights in the eyes. There are color spaces for which this algorithm produces a green cast; if this is encountered, the desaturate option provides a suitable transformation alternative.

Use of the tool first requires zooming to 100%; double-clicking the display will eventually toggle to it. Then, the eye centers are selected directly in the display with the mouse; the selections are marked with a cross. There are threshold and radius sliders to control the process, as well as a percent for the desaturate if selected. Follow the instructions in the tool parameters box.
