After correcting the green, you can also adjust the red and blue if necessary.[View full size image]This photo needs some additional tweaking to increase the saturation now that we've taken out the excess color. It also needs croppingand some brightness and contrast adjustment, and some spot removal. Be sure to see the final picture in the color section. It's a bigimprovement.Fixing Red EyeYou've seen red eye. It's not a problem in black-and-white photos that you colorize, but it's often a problem in color pictures of people andanimals taken with a flash camera.Basically what happens is that the flash reflects off the blood vessels at the back of the eye and puts an eerie, red glow into the pupils ofanyone looking straight at the flash. Some animals, by the way, can also display a similar phenomenon called green eye, which is causedby the flash reflecting off the back of the eye. You can avoid this if you make sure that your portrait subject, human or otherwise, isn'tlooking directly at the flash. Also, make sure that there's plenty of light in the room so that the subject's pupils have contracted as small aspossible.You may think red eye is easily fixed these days with a quick application of the Red Eye tool, but this magic solution doesn't work in allcases. Figure 22.4 shows a portrait of a blue-eyed cat suffering from serious red eye. This one was shot in a dark room and the flashcaught the cat staring wide-eyed. If we correct the off-color eyes, it will be a nice picture. But the large red area overwhelms the Red Eyetoolit doesn't know where to apply its magicso we'll have to step in with a manual repair.
