A70 Red-Eye Prob

[nooks]

I am getting photos of with red-eye. I have the Red Eye function on? Anything else I can do?

I have the same problem to.

I'm not a people photographer, so most of my pictures are action, animals or landscapes. So never tried to fix it.

Once i got someone to look from 2 mtrs back directly at the flash so it though the red-eye might work if they look at it directly. No luck

This is a common topic so I suggest you search this forum for red eye and re-eye!

In a nutshell - to reduce red-eye - use red eye reduction. Get the subject to look at the camera. Raise the room lighting and don't use any zoom.

Otherwise - use an external flash gun with a flash sync to work off the A70's flash as a trigger or - use software like PSP which has a great re-eye removal tool.

Why do people suggest folks look at the camera to reduce red-eye? This increases the chance of red-eye!

Red-eye occurs when light from the flash (or other light source like a flash light, car head lights...) enters the eye, bounces off the retinea and enters the camera lens. For this to happen the eye(s) must be basically looking at the light source, the camera or in between.

By looking at the camera, the lens is lined up exactly with the subjects iris. Snap easy to get any bounced light off the retina. Look AWAY from the camera. Watch the birdie, not the camera.

I've actualy taken both shots, and both have red eye.

I've taken a snapshot of some looking at about 15-45 degrees away from the camera. And it intreagued me that there was still red-eye, its on one of my pictures somewhere on my comp, way to many to find it.

External flash, i haven't seen anywhere on the A70 that it can be linked to. Unless you press the shutter and the flash with one in each hand. I haven't seen a device yet to do it with one. Haven't looked for it i might add.

I think the problem is the little red bulb. In the manual it says that to reduce red eye, get the subjects to stare directly at the red thing below the flash. I think this sends out a faint light and thats meant to do the job.

The problem is that it does bugger all, the good reductions ive seen are when the actual flash has a pre-flash, to alow the puples in the eye to close up a bit, therefore no red-eye.

Yes, you can have red eye when someone is looking away at 45 degrees. There is no cut and dried "do this and never get red eye" rule. It's all subjective to light levels, other light sources, pupil size, distance from flash to lens, and even colour of the eye (brown eye are less likely to have red eye.)

Red eye is prone to occur in point and shoot cameras as the flash is so close to the lens. Some cameras try to compensate by having pop up flashes, but it never cures it.

Personally, other than experimenting, I've never used any camera's red-eye gimmick.

Because the A70 doesn't use a preflash any flash gun attached to a flash sync trigger should work. I use a very old flashgun attached to a bar that attaches to the tripod mount on the A70. The flash is triggered by the A70's own flash - there is no electical or physical connection. It works a treat and allows me to take flash pictures at 1/250th of a second at f8. This give brill pictures

For some reason brighter lighting reduces the chance of red eye.

I have to agree that the red red-eye reduction lamp is a bit of a waste of space! I haven't a clue why it sometimes works and sometime doesn't. I was just repeating the advice given in the manual. Post processing/external flash have been my best solutions. The former when I can't be bothered with the big flash gun.

The reason brighter lights reduce red-eye is that the pupil shuts down.

Trying to shut down the pupil is why red-eye gimmicks exist on cameras. The subject looks at the bright light and the pupil should shut down, then before the eye can open up again (it's slower opening then shutting) you snap the picture. I've never thought blinding your subjects was nice. The flash is bad enough.
