I applied the redeye tool for my image, but after applying it, I do not see any major difference… How can I remove the red eyes in that image?
Simply select the Red Eye Tool, then click-drag on the image to draw a box around the red eye... you may need to click-drag a couple times to get the entire eye.
Perhaps a better method is to use the Desaturation Tool and simply brush away the color yourself. All the Red Eye Tool does is apply desaturation to the center portion of the area you click-drag to create. By using the Desaturation Tool, you have far more control over the amount of desaturation in addition to the actual area of desaturation.
