I just shot a wedding on New Years and for some reason almost all the ceremony shots have red eye. That's never happened before, I don't know if any of my shots have ever had red eye, let alone so many!
Any suggestions why? And any suggestions on how to quickly get rid of it?
Salut,

If you have been using a flash unit that has auto-redeye reduction, check to make sure it's still working. If it stops functioning, you got redeye if the flash is anywhere near the lens axis. Easiest way to check it is set camera on self timer in flash mode and go around in front and watch it; you should get a high-paced flicker of flash before the "big bang." If you're using the camera's own built in flash, check your menus to be sure auto-redeye reduction is enabled, you may have switched it off accidentally.
Redeye is the reflection of light off the blood vessels in the eye, and is ectremely noticeable in low light situations where subject's pupils are fully dilated. The strobing of the pre-flash causes the pupils to contract before the real flash goes off, so there's virtually no reflection from those blood vessels.
If you haven't changed your flash unit or its positioning, I don't know offhand what else it could be. This is why pro's use speedlights mounted to the side of the cam on underslung brackets, btw: they are enough off-axis that the reflections don't come back to the lens. They are better at providing a slight "modelling" effect also, as compared to in-line flashes, which give totally flat light.

| hmm well I'm using a Canon 550EX. Never did anything different than normal except 90% of the shots were in low light which is darker than I'd normally shoot in. But yea, you guys are probably right about the flash position. The softbox I wanted was in at the camera store so to get enough light I had to use a direct flash most of the time. Ugh. Still look good, though.(except for the devil-eyes of course). |

If you're using a speedlight, then I've seen red eye as a result of the subject being a long distance away. If I use a 70-200 and speedlight in a dark setting, then there are chances I'll get red eye. Like Bear said, double check your flash settings on the camera, you may have not set it up for red-eye, or TTL.

in low light people's pupils are dilated so there's more of the iris visible, ergo a bigger surface to reflect the flash. the whole mission of red-eye reduction is to shine a bright light at the subject to constrict the pupils, minimizing the surface area.
something s simple as a penlight shining in their eyes will also do the trick in the absence of anything better.
as for fixing it...ugh. one by one...clone clone burn burn clone clone burn burn. |

I've read some good articles against the use of red-eye reduction settings. More often than not it creates an unnatural, startled look on the subject. I'd rather have natural photos and have to fix them a bit in PS than have startled people with nice eyes. If you're doing a specific portrait you can usually get away with it by warning people that there's a pre-flash, but in candid situations you can't do that. I'm sure you would have normally used a Stofen or something similar, which is a big help. Bounce flash is also good, as is an off-camera flash cord. I think I'm gonna pick one of those up.

| Fred Miranda (I think) has a PS action that helps remove red eye. You marquee the eyes with red eye and play the action and it fixes them. Certainly quicker than doing it by hand. |
