over expose your photo by 2 stops.

To elaborate, not the WHOLE photo... use a white backdrop and put more light on the background, about 2 stops, and correctly expose the subject.

I don;t know if this is the sort of effect you are trying to achieve but here are a couple of examples of the best that I have managed to achieve
If this is OK for you, then here is what I did. First of all I find it impossible to achieve this effect in camera as you have to get the white balance, the lighting and the exposure all just so - which I never achieve. Also, I don;t have a sophisticated studio setup where I can easily illuminate the background and subject differentially. Both these shots were shot outside using natural light in full shade. I shoot in RAW and bracket exposure +0, +1, +2. I then adjust exposure, white balance and contrast further in the RAW editor until I get the effect I want.
Sometimes this is not enough and I have to select the background and further adjust that. I didn;t need to do that in either of these pics but then they're both B&W - which makes it easier.

I like to use a white background that's not too reflective, set the camera's white balance to custom using that background and the light available for the picture, and overexpose by one full stop.
The background in the picture above is posterboard, light is afternoon sunshine.
I also adjust levels and then the b/w points in post-processing.

White background <- Big photo with white background, used 2 strobes to lit the background, and one strobe with huge softbox to lit the model.

The 'light on white' challenge was tougher than I thought. Attempting to get a pure white background with no shadows and well-lit subject and no blown highlights...!!
I used a large sheet of white paper for the backdrop, which I lit from the front using 2x100w incandescent bulbs and a reflector to try and get rid of remaining shadows.
I was thinking (after I dismantled everything!) that it would have been nice to try lighting the sheet from behind to diffuse the light and give a more even effect.
My question: I've seen setups where the backdrop is lit from behind or underneath. What situations would that be suitable for?

This photo I did with a single halogen light (yeah, the cheapo ones), a silver reflector and sheets of white cardboard for the background. The halogen light was to the right of the orange, shining through some white cloth I hung across a frame in front of it (not too close to start a fire) to diffuse it a bit. The silver reflector (which is just reflective card I bought from my local newsagent) was on the left of the lemon about a foot away. the orange was on a table on sheets of white paper and the white cardboard sloping up and away so it would blur out. I used a half second shutter speed at about f11. I set my white balance to a grey card and voile! That was it! Just adjusted contrast a little in Canon File Viewer Utility before converting to jpeg.
EDIT: The funny side to this is that I used my wife's nail polish as the blood and because I messed about for about 45 minutes to get the right shot it soaked through 4 sheets of paper and took the varnish of the kitchen table that I set up on! I wasn't popular! :)

I have tried white fabric  and white paper  with almost identical lighting and there is definitely a difference. A 9 foot wide roll of white paper is only about $45 and well worth that. You can hang it on a long rod or (what I use) airline cable (cost about $4). With enough lighting on the paper, your bg comes out crisp white every time.

I have sucessfully used a light box (slide viewer) as the background. As it emits light it appears pure white in shots... it also creates some nice backlighting effects...
