Re: Red eye problem
The best way is to keep the flash as far away from the lens as possible. If you have the option of using an external flash, that would be a great solution. You can also use ?Bounce Mode? to change the light dispersion around the lens.
Another possible solution would be to bypass the use of flash by giving more exposure time or opening the shutter. In a case where the lighting is marginal, these actions can replace the use of flash.

That's because of the flash position being so close to the center of the lens. You are not alone with this problem as pretty well every point and shoot camera will suffer some type of flash red eye.
Some of the upper level pint and shoot have a red eye reduction mode that can be used check your manual. What this does is sends out a high intensity light so your subject's pupils will close down then the pictures is made. Others will have a red eye correction function built into the camera. If you have Photoshop I believe under tools there is a red eye correction tool. I'm using Photoshop CS4 and it's in that and I believe it's on PS 7 and PS 5 I'm not sure if Elements has it or not.
There isn't a whole lot you can do about it due to the location of the flash. The flash needs to be above the center line of the lens by at least 6 inches and even then depending on the subject to camera distance it's possible to get red eye.
It's becasue of human eye. Eye bottom is red, and when flash fires, camera captures eye bottom Red eyes function makes pre flash, for pupil to become smaller, but if it is very dark, it is not enought. There is no best solution for eyes not be be red, but shooting techniques can help You or You can try some software after.
Do you mean your subject's eyes are showing "redeye"? This is a common problem with cameras that have the flash very close to the lens. Almost every photo editing program has a tool to remove red-eye. Check your computer to see what you have installed.
In the future, most cameras have a red-eye flash setting which shoots a short flash before the main flash to close down the pupils in your subjects eyes to eliminate red-eye. You could also turn up the lights in the room...sometimes that helps.
The simple answer is that the flash on a point and shoot camera is so close to the lens that the light bounces off the back of the subjects eye and you get the red of the blood vessels. That's why cameras have a flash setting called "red eye" which is very useful when shooting in a low light situation.
This question is answered for you in the 800si user manual. By pressing the program-reset button, marked with a P top right, this will re-set all camera fuctions, but not red eye reduction-data memory-and ISO setting. To turn on red-eye, press the flash-mode button in the inside of door, turn front or rear dial untill a small "eye" appears in data panel. When selected, the flash will fire a series of small bursts before the main burst, causing the pupils to close slightly, so reducing red-eye. To turn off red-eye, select another flash mode. Resetting all custom fuctions, press and hold the ajust button in door of panel, slide main switch to LOCK then return it to ON.
There's two ways to reduce/eliminate the red-eye with your A570IS cameras. The first is at the time of exposure, by ensuring the red-eye reduction function is activated via the shooting menu (see page 28 of the manual). In shooting mode, press "menu", highlight the "tools" icon, and go down to "red-eye on/off". Toggle over to "on". That should take care of red-eye, in some, but not all cases. You can also remove red-eye after the image has been recorded (page 69 of the manual). You can isolate the red eyes if the camera doesn't automatically them for you. This should give you two shots at eliminating red-eyes. Another, often overlooked way to reduce red-eye is to zoom out and move physically closer to the subject, rather than relying on the zoom lens to get you close when shooting with flash. Hope this helps.
If the red-eye reduction is turned on, and you can verify that the pre-flash is functioning, you may need to think about shooting technique. With ultra-compact cameras, the flash is necessarily placed close to the lens. This is the worst design possible to avoid red-eye. To reduce red-eye as much as possible, ensure the red-eye reduction system is turned on (and functioning properly), and get close to the subject. I mean "physically" close, not just close by zooming. Use as little zoom as possible. If the subject is small, move closer, without relying on the zoom lens to make the subject appear closer.
While I do not have a P72, I find this problem odd. Most flash cycle times are so rapid that your grandaughter could not possible close her eyes in that time period (the travel time for the flash to fire and be reflected from the child's face is far faster than a human blink). The problem may be in pre-flash and not the flash itself. So that redeye-reducing "feature" may be responsible for your problem. Does your camera have a redeye reduction mode on the flash?
