Canon a630 Red-Eye Problem
I just received a Canon A630 today and every photo I took of my kids
this evening has very bad red-eye, regardless of the distance to the camera. The red-eye reduction is "on" but it doesn't seem to do anything. It looks to me like the red-eye lamp is the same as the auto-focus lamp (has a yellow color). Do you think I'm doing something wrong or do you think there might be something wrong with the camera? Any help would really be appreciated. Other than the red-eye, the camera takes great pictures. Thank you! Ethan |

Thank you! Ethan This is a common problem with almost all Point&Shoot cameras, both film and digital, and also with SLRs that have pop-up flashes. When the flash is close to the taking lens, the bright spot on the retina caused by the flash is visible to the camera lens. The possible solutions a 1. Use an external flash that's further from the camera lens (usually requires a high-end P&S or DSLR) 2. Turn off the flash and shoot by available light (but this generally isn't practical indoors unless you have a DSLR) 3. Use software to remove the redeye after the fact. Different cameras have different redeye reduction methods, but they annoy the subject and aren't very effective in my experience. Dave |

Canon a630 Red-Eye Problem

ps.com... I just received a Canon A630 today and every photo I took of my kids this evening has very bad red-eye, regardless of the distance to the camera. The red-eye reduction is "on" but it doesn't seem to do anything. It looks to me like the red-eye lamp is the same as the auto-focus lamp (has a yellow color). Do you think I'm doing something wrong or do you think there might be something wrong with the camera? Any help would really be appreciated. Other than the red-eye, the camera takes great pictures. Thank you! Ethan It's simply the nature of the beast. The flash (strobe) is placed too close to the camera lens, and you get a flash reflection from the subject's retina, giving you "red-eye". A "red-eye function" that means pre-flashing to force the pupil to close will only mean that you lose any chance of getting a spontaneous picture due to the delay, and will not be entirely effective in removing red-eye anyway. Just switch that function off, it's worthless. An external flash will help, especially if you can bounce the light off the ceiling - but such flashes tend to be big and rather expensive. There is no flash hot shoe on the camera, I see; there is a "high power flash" available but this, too, is designed to be mounted right next to the camera so won't help much. If you don't want redeye, and don't want to spend the time post-processing the images on a PC, the only practical solution in most cases is to take photographs without using flash at all. Good luck on that if you are indoors, by the way - the required ISO value for that would usually be on the north side of 800 and compact cameras in general suck badly at that, if they offer it at all. This kind of stuff is difficult even using a DSLR with a fast lens. You may be able to squeek by with ISO 800 (the 630 tops out at this ISO I think) but image quality is not likely to be too impressive; the maximum ISO available in a digicam tends to be something of a last-ditch desperate effort kind of thing. The built-in flash is great for use as a fill light when photographing in daylight, for example if the sun is at the subject's back so that the face is in shadow and needs a "lift". But considered as the main light-source in a photo, it's not very useful. Perhaps you can try to tape a piece of white tissue-paper in position over the flash bulb, this will diffuse and soften the light somewhat and reduce redeye, but will eat a lot of light and reduce the effective range of the flash. It depends on how much flash power you have available to play with - not a whole lot, in the case of a built-in one. You'll probably have to get close to the subject. |

Canon a630 Red-Eye Problem
But don't go too far, as guests might balk if you try to hire an ophthalmologist to administer Tropicamide or phenylephrine drops in their eyes. Just a quick fact check, Tropicamide and phenylepherine will dilate pupils not contract them. What you need is Pilocarpine, or RevEyes (but that just negates dilating drops. When I do eye photography the dilating drops help me out, doing essentially in focus red eye shots. Kids have naturally large pupils in house light so increaasing the ambient lght should help. My oldest son has very light irides and if I take his picture with a P&S camera I not only get red pupils, the iris of the eye also transmits red so it is almost imposible to correct a photograph. Can make a spooky photo. Tom |

I know what you mean about spooky photos, as I have a picture of a nephew playing a video game, and the bright red glow from his eyes makes it seem as if the alien is on his side of the video screen. |

Thanks for everyone's replies. I guess I just don't recall the red-eye
being as much of a problem with my previous camers (Canon S400), but it probably was. Thanks again! Ethan |
