Lighting with 430ex and Alien Bee B400Also, eventually I would like to move to the high key bright white backgrounds. Do you think the 400b would be powerful enough to produce that bright white background? Thanks!
Thanks for this link! I hadn't seen this one before!

Your 430ex will sit on the hot shoe of one of the receivers, and you'll need to either use the 15' sync cord that comes with the B400 or buy a shorter version of the cord to connect a receiver to a B400.
If you feel like modding them to get better performance, check out this site:

There are a lot of different options for syncing these strobes off camera including a sync chord with a splitter. Top of the line option is Pocket Wizards (you need one for the camera and one for each light), with several similar options including Radio Poppers and others (find out more at Strobist (http://strobist.blogspot.com/) and read the Lighting 101 section first). There are also some low cost options on ebay called cactus triggers, which might work fine for you also.
As far as white backgrounds it usually takes two lights to get a nice blown out pure white effect on paper depending on the size of the paper. Find out more about the technique at zarias.com (http://www.zarias.com/?p=71).
And when the alternative is cording the 430ex, and using the optical slave on the B400, you're probably going to get a few misfires on the B400 anyway. And you can forget using them outside during the day.
Regardless, I mentioned that the Cactus triggers aren't the most reliable in my first post. But they work, they're cheap, and they're better than cords unless you're only doing close-up work.
He could end up getting a set that ends up misfiring a lot. Their QC isn't very good. I've had two people shooting at meets that have just wanted to destroy the set they had. I ended up letting one borrow my PW's and the other couple just suffered through the day.
Cyber Syncs are fairly cheap with all things considering and would probably be less of a headache. He'd only need one set for the camera and the SB and then put the B400 on the optical slave.
I'd almost even prefer a sync cable. You can make one or buy one even longer than 15'.
The 430ex can be used as a slave, but it requires a 580ex or an ST-E2 be on your camera. It's triggered by an infrared signal.
If you ever do try to trigger your 430 with a 580ex on camera, just remember there will be a preflash, which will trigger your B400. And it probably won't recharge in time to go off when the real flash goes off.
If you go radio triggers, you'll need a transmitter and 2 receivers. Again you have a few options for radio triggers. From cheapest to most expensive...
Cactus or "eBay" triggers - $35 for a transmitter/receiver set, $20 for another receiver. Not that reliable out of the box, pretty good with a couple simple mods.
Alienbees CyberSyncs - Something like $60 or $70 per unit. More reliable than the Cactuses, not quite as reliable as Pocketwizards.
Elinchrom Skyports - $185 for a transmitter and receiver, $100 for additional receiver. Very nice radio triggers, as good as PocketWizards, just not industry standard
PocketWizards - $185 per unit. Each unit can act as transmitter, receiver, or both. Great range, very reliable, the industry standard.
You can also go corded, but that's no fun, and Cactus triggers are cheaper. Also, definitely check out www.strobist.com (http://www.strobist.com)
Send it back and get a new set. That's why I suggested MPEX instead of eBay or Gadget Infinity. I understand that's more of hassle, but if that's all your budget can afford then so be it. When you do get a good set, they work well.
Yes, CyberSyncs would be better. I think you have a set of ABs, so you would know better than me how well the optical slave works. I've only heard bad things about optical slaves.
If he's even considering Cactuses (and a B400) he's not shooting professionally, so a mis-fire once in a while is no big deal. Furthermore, with the mods that I linked to you should be able to get VERY reliable operation in a studio setting, and only the occasional misfire in more complex situations. I don't know what your experience with these triggers is, but I've been using them (modded) for quite a while, and they do just fine. I get at least 200 feet from mine, without line of sight (which translates to very reliable operation in the studio).

The sync cord that the AB comes with is a PC-1/4" cord. The only way to get that to work with your 430ex would be to buy about $40+ worth of adapters. And then you're limited to less than 15 feet (a 15 foot cord isn't actually going to get you 15 feet) with your 430ex, when for $15 more you have wireless freedom with the Cactus triggers.
