I'm resistant to shooting "off the cuff" green screen for clients. Like anyone not directly in our business clients tend to have a simplified view of the technique required to do it well. We use green screens in order to easily drop out the green background behind a subject and replace the background with a different image. Compositing is so easy in still photography now that one rarely even needs to bother with a green (or blue) screen but video comes at you at 30 frames a second and it would be more than a little time consuming to go into each frame and do selections, etc. so green screen is still standard if you want to layer in a different background behind a person or object in video.
Like everything there is a right way to shoot green screen and a wrong way. The wrong way is to set up a green background without lighting and hope that available light and luck will get you a clean enough background to composite. It kinda works but requires a lot of post production masking to deal with variations in tone and color that make automated background drop outs tough.
I've done half-assed green screen in the past with reasonable results but I'm shooting a big video project tomorrow for a larger ad agency. It's mostly green screen and I wanted to understand the best way to do the work and what kinds of things to watch out for. Nobody likes having to make excuses
