A Quick Photography Tutorial

Ever since camera manufacturers began putting flashes next to their cameras (which would since the early days of photography), the constant struggle has been about what to about how flashes catch people with their eyes open exactly atthe wrong time (not that you would want them to have their eyes closed). They call it "redeye" – for the way light from the flash goes straight into the eye, bounces off the retina and comes back to the camera as a bright spot of red bang in the middle of the eye. When a flash of light comes off that quickly, the eyes just don't have time to close. Well, there have been all kinds of attempts made at getting rid of it. This little photography tutorial will show you what to do with a picture where you to have a spot of redeye that you need to get rid of.

To the camera manufacturers, the preflash has always been their best bet. A camera with preflash tries to flash your eyes with a few bright shows of light so that your irises will be narrow down. With the main flash comes on, it'll catch your eyes at a time when the openings are at the narrowest. This way, there's not much chance that the light will be able to successfully go all the way in and come all the way out. 

While this method might work reasonably well sometimes, it isn't a good technique for other reasons as Diana from Jotolio photography now explains. People catch those flashes of light, they think the picture has been taken, and they break the pose. So it would really be best if you could just take a picture any way you will, redeye or not, and let this photography tutorial show you how to fix it later on in the computer.

Why call it fixing it in the computer? It's Photoshop all the way. What you need is a little Photoshop tutorial is this photography tutorial. CS4 and CS5 actually have a great purpose-built redeye tool right there. Load the picture, select the right tool, show the program the general location of where the redeye is, and it'll go to work right there. What do you do if you have an older version of Photoshop that doesn't have redeye removal though? 

Well, it's easy enough to do it manually. All you need to do is to get a brush in Photoshop, set the hardness to about 75%, change the mode to Normal, and paint the redeye out. Of course, you can't paint just any color in, or the eyes look completely odd. What you need to do is to click on the black and white icon that you see in your toolbox right above the color palette. When you paint after you do this, the natural colors of the eyes are retained, while the red is taken out.
