Video projection backgrounds

When shooting on location, we’re often faced with plain, white walled rooms.  The good news is in these rooms, there’s usually a video projector suspended in a ceiling.  One can quickly pull up a company logo or product, drop it on a PowerPoint slides and viola, you have an instant background.  If the image doesn’t align where you want it, it’s easy enough to change the position of the element on the slide so it lands exactly where you need it.  The key to making this effect look good is to keep the light illuminating your subject off the projection screen.  The flipchart in the photo has been purposely placed there to block some spill from one of our lights.  Here’s what it looked like through the camera.
