Red Eyes photographing is all very new to me, but I do love it! Please help me- I know this is a silly question but it's quite discouraging.

Zara, The retina at the back of the human eye (inside it) has a very high concentration of capillaries very close to the surface of the retina. Red-eye is the reflection of the flash from the blood in these capillaries at the back of the eye. Several conditions contribute to red-eye: (a) Subjects pupils are wide open due to low light. Alcohol consumption also dilates (widens) the pupils. Parties with very low lighting and drinking, such as wedding receptions, often create the widest pupils. Babies and toddlers also tend to have their pupils open wider than adults do. (b) Subject looking directly at the camera lens. (c) Flash is mounted very close to the camera lens. Not all of these *must* be present, but each one of these increases the risk of red-eye. The "red-eye reduction" feature on many cameras fires pre-flashes to close the subject pupils before the shutter opens and main flash occurs. Unfortunately, this often does not work very well. The pupils usually do not react and constrict fast enough, nor do they get small enough to eliminate it. Solutions: -- John
