Another SB800 ??

Postby BBJ on Sat Aug 30, 2008 3:16 pm

Hi All you flash people who knows the ins and outs of these things!! I am wanting to know is there a way to speed up the pre flashes when you have it set to stop red eye? as at times i have used it to take a shot and people pose and it take so long for the main flash to get the shot and can be a pain at times so maybe i am doing it all wrong.

Cheers

Question is, why would you turn on red-eye reduction for this flash? Does it really create some red-eye problem when the flash is mounted on camera? (without red-eye reduction)

Redeye occurs when the flash is firing at the same axis as the lens. ie, built in flash on the P&S cameras. With the SB800, given ability to bounce off walls & ceiling, plus the extra height gained on camera, it should have very little effect on the 'red-eye' problem.

What are your settings? Any sample shot of problem you trying to solve?

1- Try rotating the flash away from the lens axis (instead of pointing it straight), eg. aim it up 45deg or rotate it away from the dead front position.
2- Try firing the flash off camera. I'm assuming you are running D2 cameras, so you might need a wireless trigger or a SC28/29 sync cables to try this.

Thanks Yi-p, I am not up to playing with the flash a lot but have in the past had a few pics where the red eye has been a problem and had not thought about adjusting angle of flash as some places i have been the ceilings have been very high so thought bouncing would not be good. It was just a thought as the time it takes for the preflashes seems slow and was curious if could be made faster. I hate using flash unless i really have to.LOL

If i can find some pics i will post them.

Or close to it.

Bouncing will help, as will moving the flash off camera.

The easiest way, John, would be to grab a SC-29, and then just hold the flash at arm's length when you make the image. Obviously, disable red-eye for this.

A 45deg up with bounce card out should solve most of your problems. Or stick a piece of white cardboard with rubberband to the head of your flash... it works the same way but has much larger area to 'bounce' off from.
