Red eye question

I was at our work's children's Christmas party on Sunday and I took along my gear to see if I could catch a nice shot or two of our children. I used a basic ebay diffuser to try to reduce the glare of the flash and I got some cracking shots. One thing I've noticed though is that in every single shot, there is red eye. Every single shot! Some I took with the 50mm f1.8, some with the 70-210 f2.8 (at all focal distances) and one with the 105 f2.8.

I had the iso at 800 and the shutter at 1/200th (flash sync) and shot in aperture priority with the ap wide open.

Any suggestions why this is? CS3 is great at getting rid of it but it's a pain to have to go through that with every picture. Luckily I'm getting better so my delete percentage is dropping .

Re: Red eye question

Basically your flash is dead in line with the pupil and is illuminating the retina. If you can detach your flash and move it a little bit above the subject or to one side the problem will disappear. Failing that, if your camera has it, use the anti red eye. All that does is give a small pre flash so the iris of the eye closes a lot before the exposure.

Re: Red eye question

Red eye can be a pain.....it normally happens when the room lighting is a bit dull or dark.....red eye reduction or a pre flash does not allways work either.....bounce flash is one option and the more power you have in the flash gun the better this is what you pay your money for......but if you only use flash every so often its money wasted.....so its not allways an easy answer....I would go for bounce flash and to open your lens up and a ISO of 800 or more will help....of course you could ask or wait for the person to not look directly into the camera lens.....but often the shot would be missed if you do this.....I often get rid of red eye in photoshop but it can take a couple of evenings to do this......what a pain!....so its plenty of power and bounce flash and your lens set at f4 or wider and focus carefully on your children...

Re: Red eye question

Thanks for the replies . I don't have a flashgun and was just using the onboard canon one so I guess that's it. I was just a little thrown by the fact that even the people who were looking almost at 90 degrees away from my line of fire still had redeye. Looks like I'll need to speak to Santa about a new flashgun...

Re: Red eye question

Oh I did not realise that you was using the on board flash and that just makes it worse!

Re: Red eye question

Using the on-board flashgun is one of the biggest reasons for red eye. Put simply, the closer the flash unit is to the lens, the more chance of red-eye as the light is going straight out and straight back again, shining on the retina on the way. Remember, the pupil of the eye is not black, it is an empty hole. It looks black because inside the eye is dark but if light is shone straight into it you can see the back of the eye.

An on-board flash is very non-directional, it shines the light out all over the place and so even people at an angle to the camera can exhibit red eye. So is there nothing you can do? Good news, there is....

Your on-board flash can't be angled as such but that doesn't mean you can't angle it's output. Try this: take a piece of white card, a couple of inches square, and tape it to the bottom of your flash, angling it about 30 degrees upwards. Now take a photo of someone straight ahead of you. Look, no red-eye! Why? Because the light is not going straight to your subject but instead is being bounced off the ceiling so does not have a straight out-in path.

Of course, as Fi said, the best bet is a separate flash unit. Even on camera, it will be considerably higher than the on-board flash so will reduce red-eye. It won't get rid altogether though but if you get a flashgun with a bounce head, one that can swivel upwards and/or sideways, you can bounce the flash off any direction and give much more pleasing tones to your pictures as well as eliminating red-eye altogether

Cheers,
Rob

Re: Red eye question

definately can be Des, although again it has its limitations, the lens you are using has a bearing on onboard flash, for example i cant use it with my Sigma as it creates a huge shadow at the bottom of the image, and of course the subject has to be pretty near to the camera the light form an onboard flash just isnt strong enough to reach too far.

Re: Red eye question

Good discussion guys and gals. Thanks for your input. Fiona - thanks for the offer - I just decided to take my stuff with me at the last minute but it was at the Inchyra so I guess I could have maybe stopped by and picked one up. Older and wiser though - I didn't realise that it would have had that effect.

As for bouncing the onboard flash, I'll remember that for indoors shots but the hall was so big it'd have been lost before getting back from the ceiling.

I'm tempted by the 550 in the for sale ads.....

Re: Red eye question

An update on this. I used the speedlite for the first time at the weekend. I haven't read and digested the manual yet so I used the diffuser and bounced the flash off the ceiling (it was my daughter's birthday party). The flash was able to be positioned at any angle so I could use the ceiling bounce in portrait or landscape and it really softened the lighting. There was the odd occasion when the shot was over exposed but that was the exception so I'll need to do more reading.

The real result though was zero red eye. Even when I used the flash straight on (for distance shots) there was nothing. I can't wait to get better at this and it's given me a real interest in the mechanics of flash photography.
