Default HSS outside at midday, fill flash, bracket required?

I'm shooting some wedding pictures on a beach at midday this weekend. Two*20D/range of lenses 12-200mm, 580EX/550EX on high speed sync as fill flash. My question is do I need to bother with a flash bracket for these shots? I suspect since there'll be so much light the pupils will be very small and the chance of red eye is minimal, compared with the hastle of using a bracket.

I'm not so worried about the quality of the light in this situation (ie direct flash), but opinions on this from anyone with experience is also welcome.

If you flop the camera over into vertical/portrait orientation, aren't you going to have the same "shadow on the side" problem that you would have indoors? I agree that with a lot of daylight around, it won't be as much of a problem as indoors.

I always look at it this way: What would it hurt?

I don't imagine there'll be anything behind them for shadows to fall on, but that's a good point. I'm more worried about red eye and how much it'd slow my workflow down when I correct it.

I don't think red eye would be a problem outdoors during midday unless you happen to be shooting while a solar eclipse was occurring above you. Better check the weather report just in case.

The red-eye phenomenon happens when the pupils are large and dilated because of dim light levels. Personally, I have never seen red-eye from shots taken during the middle of the day, not even with P&S cameras which are notorious for this problem because of the flash being too close to the lens. Also your flash is elevated several inches higher from the lens than a typical P&S camera which also helps. So in my humble opinion, you shouldn't have a problem unless it gets very dark. For instance, if you shoot in a covered corridor around sunset.

FYI, this problem is usually worse with small children and animals.

Good luck!

We're now shooting on a beach? Or is this something else you've got on as well.

As Kaplan said, you won't get redeye outside in bright conditions.

The "creative" pictures are on a beach, outside government house, on the wharf, and maybe aronud parliment, depending on the weather.

No opinion but a question - is HSS used in this situation to allow the higher shutter speed needed to control ambient light in a typical beach setting?

Pretty much. Because i'll be shooting with wide apertures on a bright day the shutter speed will probably be faster than 1/250th, which is the fastest the 20D can use standard flash at. HSS lets you use any shutter speed. The EOS flash bible has a great explaination of how it works and why, and has to do with the way the shutter works.
