The Red Eye Problem:

Red-eye is caused by the camera photographing a reflection of the back of a subject's eye. Because the pupil dialates for darkness, people with large eyes, or in dark areas are particularly vulnerable. Most cameras sold now have a red-eye reduction function that works fairly well. Aside from these functions, or just avoiding bad situations, the only sollutions come after your photos have been developed. One option is to purchase an inexpensive "red-eye pen" (you can buy these anywhere, walmart, craft store etc), it is a light green dye that you put onto your photos, neutralizing the red eyes. Another option is order digital red-eye reduction, which makes copies of your photos, and digitally removes the red eyes. This is more costly, but for important photos is probably worth the expense.
