QUESTION: I have two
small children and we take a lot of pictures of them. The pictures taken
outdoors look great but inside the house there are problems. In every
picture where the children face the camera their eyes have a red
appearance. We use the red eye reduction feature on the camera but it does
not seem to make any difference. What can we do to make the eyes appear
normal? ANSWER: This is a common problem in photography. It has become
more pronounced as cameras with built-in flashes have become smaller in
size. The light from the flash hits the face and reflects back to the
camera to make the picture. If the angle made by the light going from the
flash to the eyes and the reflection from the eyes to the lens is small
and the pupil of the eyes are large then the red lining at the back of the
eyeballs will show in the picture. If reflected light
from the back of the eyes is eliminated or reduced sufficiently then the
red eye problem will go away. The red eye reduction feature on the camera
attempts to deal with this by shining light on the eyes before the picture
is made. This is an attempt to cause the pupil (opening in the front of
the eye) to become small so that very little reflected light will escape
from the eye. For some reason blonde haired, blue eyed children seem to be
immune to this tactic. The red eye reduction technique used by
professional photographers is to increase the distance between the flash
and the lens. This is one of the reasons that you will see a flash mounted
on a bracket above or to the upper left of the camera at weddings,
parties, etc. Total elimination of red eye is accomplished by
reflecting the flash light from the ceiling. This normally is done by
using a flash with a head that rotates so that is can either point forward
or point at the ceiling. Since no camera is made with a rotating head this
technique requires the use of a camera that will accept an add-on flash.
The rotating head flash, sometimes called a bounce flash, has to be of
medium to large power so that light reflected from the ceiling will still
be bright enough to properly illuminate the scene. An additional bonus
of using bounce flash is that the lighting appears more natural than
direct flash. Direct flash tends give a poorly exposed picture if the main
subjects are both close and far away from the camera. The close subject
will be too brightly lit while the far away subject will appear to be too
dark. Reflecting the flash
