Camera red eye is something everyone with a digital camera will run into
sooner later... Take a picture of a friend in dim indoor light and automatically a blinding flash bounces off of the face of your subject.
Later, when you view the picture, your friend's eye-balls are illuminated in a
unearthly bright red!
Red eye is a common problem in photographs. However, it doesn't have to be a problem. You can stop red eye in it's tracks by eliminating it before it even starts.
What is red eye?
A reflection of the camera flash from the back of the eye ball. The flash makes the pupils in the eyes of a subject light up in a strange bright red.
Red eye is always caused by on camera flash because the angle of the camera flash is too close to the camera lens. The closer the flash is to the camera lens, the more likely you will be to have
camera red eye.
Why is red eye undesirable?
Bright red eyes in photos makes your pictures look very weird. It's hard to enjoy a photo of a friend if they look strangely alien in the picture. (Unless you're into that kind of stuff!)
How to Permanently Get Rid of Red Eye
It is actually quite simple:
Stop Using the On Camera Flash!
Flash is what causes the problem in the first place. Fix the problem by eliminating the source.
Flash is really unnecessary (for the most part). In fact, the flash is there on your camera because it makes consumers happy, and NOT because it makes wonderful photos. Because it doesn't!
Flash creates the dreaded camera red eyes in your photos, not to mention that it's brightness also makes harsh shadows everywhere. End result: terrible looking, unflattering, unnatural pictures.
What should you do instead?
The answer is to work with the light that is available. This is what professional photographers already do, and if you do this too, you'll be a big step ahead in your photography skills.
Look for alternative light sources.
If you are indoors, turn on more indoor lights or move to a nearby window. The soft, indirect light that comes through a window makes lovely portraits. Another option would be to move outdoors for your photos.
Adjust your camera settings.
Is natural light not an option? Maybe there are no indoor windows, or it is night
time? Change the settings on your camera to a higher iso. This helps you camera to "see" better in lower light conditions and reduces the need for a flash.
My Canon Rebel XTi has a 1600 iso that is excellent for unavoidable low light
shots.
Turn to pro solutions.
An external flash is a more advanced solution. This is a camera flash, too, but moving it off camera and using it from a different angle will prevent red eye. This is what quite a few professional photographers use
to control the lighting in their photos.
Most people use their on camera flash just because it's there. They don't really think about it, and just let the camera do the thinking for them.
Take control of the lighting in your pictures.
Turn off the camera's automatic flash and you will permanently end your
camera red eye problem. Instead using the on camera flash, try taking advantage of the natural light around you.
