Redeye Issue

I am hoping for some help as I am not much of a photographer, yet anyway. I
bought the Cannon A85 back in July and have taken about 400 shots with it
since then. I have noticed that I have an issue with Redeye on a handful of
my indoor shots. I do have the redeye setting on, but that does not seem to
always do the trick.

I was hoping that someone could help me out with some advice. It is not
consistent on every shot, but I would like to try to figure what is wrong or
what I am doing wrong.

Thanks in advance for any help.

It's not what you are doing. When the flash is on almost the same plane as
the lens/sensor, you are going to have this problem. An external flash
helps a lot, especially when you can bounce it off of a ceiling.

Redeye reduction on the camera fires several pre-flashes to hopefully adjust
the iris of the subject (shrink the opening). I said hopefully because the
results vary a lot from subject to subject (humans have very different
response times and different variations of the amount of iris reduction and
different internal reflections from the eye itself).

The built-in flash on almost all cameras is a convenience with limited
performance.

Thanks for the quick response. Are you recommending the external flash? I
have seen them for this Cannon for about $70, but I was not if it was worth
it.

Is it easier to just keep things as in and continue to "fix" them prior to
printing?

Red eye occurs when the flash is too close to the lens. It is also more
prevalent with blue-eyed people. Solutions:

1. If possible, use a flash which can be mounted away from lens axis.
2. Try bounce flash, if you have that capability.
3. Use available light as much as possible.

If red-eye reduction worked like it should in theory then anyone using
a high resolution camera would catch the abnormal pin size pupil.
Believe me I know. It doesn't look natural.
What also doesn't look natural is post processing red-eye and end up
with pupils larger than they should be. Now you have the task of not
only reducing the pupil's circumference, you have to put some reflection
of flash in the pupil otherwise it won't look normal or natural.
Did someone say it would cost you $70 for a bounce flash? It's well
worth it. Think of the times you may need to capture far beyond what
your integrated flash provides. Think about how nice it would be to
illuminate your subject and also finally see what is outside that window
next to them.

are you holding the button 1/2 way down until you hear the beep before
pushing it all the way. I had a lot of red eyes until I realized this is
how the redeye reduction was supposed to work on the Pro1. Used it for 2
months before a friend told me that. Haven't had one red eye since.

I have an A40. Since neither this nor the A85 have an external shoe, how
does the external flash work. The internal flash is still going to fire.
Different situation on the G series and up. I can't understand why canon
couldn't provide a miniature plug to accomadate an external flash cord.
Flash could incorporate a bracket that screws into tripod socket.

Just using an external flash won't do it. That is why us wedding
photographers put the flash on a bracket. That flash should be about 12
inches above the lens. This works very well.

True but, in many cases, bounce flash works well too.

I have been holding the button down, you need to on this model before it
will even shoot.
I don't have it all the time, but enough of the time that I wanted to look
at options.

Thanks,
