It's a white seemless background.

They are actually kind of tricky to light.

I did one a while ago and it made me a bit crazy. You have to light the backgroud and the subject seperately.

Make sure that the background is very evenly lit and about 2 stops brighter than the subject.

There's a few tutorials on how to do this that you can find in photography forums.

Good luck.
 
There is no such thing as a dumb question; only dumb people.

(Relax; I'm not calling you dumb, just making a dumb joke)

This is the basic jist of it.

That's actually a good question! The trick that makes lighting a seamless white background easy is the use of a "cyc" wall (short for cyclorama) that is a smooth surface with curved corners so you don't have shadows in the corner. There are also cyc lights that are designed to hang over the cyc and cast an even light on surface of the cyc.

Here's a picture of a professional cyc: http://www.astcyc.com/html/wooden.htm
 
Wouldn't it also be necessary to keep the talent a good distance from the backdrop in order to avoid their shadows appearing on the wall and to keep the "white" from bleeding onto them?
 
Honestly the shoot in front of a greenscreen suggestion isn't a bad one if you don't have the space/walls/lights to do it the "right" way. About half of my Sci-Fest entry was against all white and I shot it against all white without the space/walls/lights to do it and it caused me serious headaches in post.

Yeah... I finally had a GOOD idea.
 
But everything you need to do to make the white look good, you have to do for the greenscreen -- even lighting, watching shadows, etc.. Just switch out the green with white and you're already there.

I knew you'd say that. :)

In my particular case, it would have been a lot easier against green because I didn't have the equipment to do either correctly, so I would have to do touch up in post regardless. Rotoscoping against green is easier than rotoscoping against white in my book.
 
No, I understood. Just sayin' that in general, it's the same amount of work, so why add another step in post?

Also, with green, you have to worry about green spill on your actors and other hazards of greenscreen.
 
I know this has been said to death by David, but remember you are shooting with DV, so keying the green to white will never give you as nice results as you could get just having white.
Another option would be to find a photo studio, rent the location for a couple hours, they will have all sorts of backdrops, including white, that you can work with.
