How to reduce red eye in digital photography

How to reduce red eye in digital photography? This is a good question. All to often a great picture is tainted by the red glare in one or both of the eyes of the subjects. There is some digital photo editing software available to help with that. However, sometimes this leaves the picture remaining to look fake, or distorted.

What if there was a way to minimize or prevent red eye all together so that you are able to view the picture as it really is. This would be instead of having to use a program to delete or change parts of the picture.

The theory that red-eye should not happen, just does not seem to stand up to the red-eye devil. That time consuming little monster that ruins so many great pictures.

The incorrect color in the eyes, whether red-eye, yellow-eye, or green-eye is very simply unwanted flash reduction. This flash reduction bounces back into the cameral lens from the subject's retinas.

There are ways to do this. Here is how.

  • When using the cameras on board flash, the camera will usually use a short pre-flash to slow down the subject's pupil for the main flash and exposure. This was designed with the hope that the pre-flash will narrow down the reflex cone to miss the cameral lens completely. This process has only had partial success. (Hint, this will probably not work at all on a person who is intoxicated)
  • Ambient light that is increased can help to reduce red-eye. This will both narrow your subject's pupils, and will also allow for a lower flash power to dim the reflex.
  • Sobriety is a big thing. As listed above, even with some of the best flash technology, subjects that are intoxicated will likely have a red-eye look regardless. Inebriation does not look all that great in photos, so make sure that the pictures that you want to save are taken early.
  • Averted gaze is a good way to limit the red-eye. The reason is that if a person is looking away from the flash, it is less likely that the eye will react the same way.
  • Move a little closer. When you are closer to your subject, it widens the flash subject lens. This is the angle be beyond the width of the reflex cone. This will then evade the reflex.
  • Using an external flash will also help. This should be positioned 5 degrees away from your camera lens. This will be as seen by the subject. In order to set this to 5 degrees, it is simply about 1 ½ of the distance. So about 6 feet in many situations.
  • Using bounce of the flash to redirect the reflex away from your lens.
These ideas will help to reduce the chance of red-eye shots. However, in some cases if these measures are taken to the extreme, you end up with shadows.

Keep in mind that the position around the lens will not make any difference with regard to red-eye due to the cylindrical symmetry of the flash retina system.

There are many color sampler tools and other options that can be used for taking pictures with less red eye. It is also a good idea to take these pictures from different views. This way you can at least have that picture in that instance with some view, which will not have red-eye.

This should help to reduce the red-eye in digital photography. Now all you have to do is practice. The perfect picture waits for you right around the retina.
