If you've ever taken a flash photo at night or in a dark room, you have ran into this problem, which is called red eye. Red eye is just the flash reflecting off the back of the subject's retina. This is my son Cobby with some serious red eye going on but that's okay because I can fix it with just one click in Photoshop CS4 using the Red Eye tool. The Red Eye tool is located behind the Spot Healing Brush right here in the Toolbox. I'm going to select the Red Eye tool and then I'll go up to the Options bar and take a look at the options there. I usually make the Pupil Size option smaller than the default of 50% because I found that if the subject has lots of red in his or her face, this tool will sometimes pick up that as well and try to correct to correct it, thinking that it's red eye.
So I'm going to lower that Amount, I'll start with maybe 20% and if it doesn't work I can always come in and change this Amount. The Darken Amount determines the darkness of the gray or light black that's going to be used to replace the red in Cobby's eyes. I'll leave that at its default to start. This really is a one-click process. All I have to do is come over one of the red eyes, click on the red and Photoshop fixes it. I'll do the same in the other eye, as you can see this tool leaves some detail in the eye so the results usually look pretty realistic.
So the next time you end up with a shot with serious red eye, don't put it in the reject file, just use Photoshop's Red Eye tool to fix the problem.
