I just purchased my alien bees start-up kit. here's my set up.

canon digital rebel xt
alien bees 320watt B800 flash unit w/ umbrella
pc connection adapter for hot shoe connected to my camera

when i take pictures w/ this setup, they turn out like this...and i know it's probably something just very simple, but it's pissing me off to no end. help would be greatly appreciated. i know if there's anyone out there that knows what's causing this, they're on here.

thank so much for your time. it's much appreciated.

Jed,

The shutter speed on your camerawastoo fast (1/1000") and the flash couldn't sync properly. I don't know what the max flash sync speed of your Rebel is, but check it in the camera manual. On Nikon D50 it's 1/500", on my Fuji S9500 it's up to 1/1000". On Rebel it should be either 1/250" or 1/125".

Set the shutter speed to a slower value and test it again, it should work just fine.

Also it would be a good idea to use your camera with a studio flash in Manual mode.


Congrats on your new flash kit.

Yes, you definately have the shutter speed set too high. Look in your camera manual to see what it says is the fastest speed you can use. Bear in mind, that TTL sync speeds will NOT apply. Look for the external flash sync speed. You will also need to set your camera to manual operation for exposure, where you must set both the shutter speed and the aperature. If you do not have one, I would also suggest getting a flash meter.

I second that, a flashmeter, even a cheap one, can help you a lot.

The max external flash sync speed for you camera is 1/200.

Have fun with your new toy

Hi Jedmag,

Your first thing to do is go to B & H or E-Bay and get a FLASH meter. TTL just does not function with studio lights so You will have to use your camera in Manual mode. It is not difficult. I use Travel light 750's and I always set My Aperture to F-8 and My shutter speed to 1/60th. Just set your main light to F-8 and Your fill light to F 5.6 or F-11 depending on the subject and the results you want and like.

You have very good lights so You should not have any problems with lighting properly. You can always reverse the Main and fill light ratio's if needed for your subject if needed.

Just make positive you get a "FLASH" meter and not just a exposure meter when you order one.

Remember the closer you can position your umbrella's to the subject the softer the lighting will be. A lens of 85mm and greater will be much better for portraits then a 50mm or a wide angle. Also make sure your subject is not to close to the background because of shadows.

I hope this will be of Help to you.
