use the sponge tool in photoshop to desaturate the red.... in future set your camera to red eye reduction, it works sometimes but not always..

Red eyes...
Some eyes are more sensitive than other...

You need a good light conditions to make a photo... :wink:
the flash is very strong and the pupil of the people is dilated as it's dark environment...

If you are inside your house... Recreate a better lighting and put some extra lights to help...
There is no solution than bring extra luminosity to assist the pupil to become normal...
Without joke, I have try with a torch before to take a photo (home)
Even professsional photograph put a lot of light to have a good photo (with diffusion)

If you flash outside on a sunny day you will never get red eyes! :idea:

Some suggestions before you shoot the picture.

1. Check to see if your camera has an option for red-eye reduction, you may be using this already. This fires a short flash before the shot to help close the pupils.

2. Turn on indoor lights, particularly behind you so the subjects are facing the light. A table lamp or something similar is helpful. Don't stand directly in front of the light as this will block it. This will close their pupils somewhat.

3. You can also have the subjects not look directly at the camera, ask them to look at your shoulder.

After you shoot, there are several software programs that can help eliminate the red-eye.

Very good explanations...
-----------------------------
It's a lot to understand the problem (not fixing it) of red eyes.
Your english better than mine anyway... :wink:

If you have a flash that can bounce try bouncing on the ceiling of wall, this will give you a indirect light that will usually not produce red eyes.
This will help removing strong shadows and give you a softer light.

Also, lets not forget, that using flash "off camera" on a stand, or with a bracket is another way to help avoid red eye. If you're using the "in camera" flash, of course, the only options are in post processing.

As touched upon, the reason for red eye is the flash illuminating the shiny retina of the eye. When the flash is placed close to the lens, the light reflects directly back causing the red eye effect. Once the angle is changed, the reflection is directed away from the lens thus removing the problem all together, and the reason Dougs suggestion is helpful about having people look away from the camera. The reason preflash, or adding brighter lights helps is because it causes the pupil to close more, reducing the chance for reflection, but still isn't always 100% effective. And bouncing has other advantages as mentioned by alexphotos. A good flash with accessories is a great investment, which can pay off with better photos for years. Try purchasing one that you'll be able to use with the complete system of cameras if you intend to upgrade in the future. Like lenses, try getting the best possible one you can afford from the start, and you won't be needing to upgrade it later on too. Just one more reason to stay with better name manufactures who have produced "pro" market equipment for years. :wink:

Enjoyable, and informative thread everyone, thanks!

Good suggestions from everyone. The Kodak C663 looks like a nice camera, but is somewhat limited in terms of flash flexibility.
