These are the front projection units that I wrote about. You only
need these to shoot film, digital capture would be better and easier
with green screen.
These work as well as or better with digital than they did with film.
There's less time required in post processing than with green screen &
getting the lighting setup right is a lot less fussy than with green
screen - at least based on my experience shooting green screen it is.
I have yet to try green screen, though it's on my to-do list. I'd expect
that success with it is dependent on lighting the green screen very,
*very* evenly. Background extraction tools in Ps are quite finicky to use.
But I've played with a new feature in CS5 that helps with this: the Auto
Edge Detect tool in Refine Selection is very smart. It does a great job
with texture, hair, etc. I've been able to lift a flower off a
background, use Content Aware Fill to create plausible new background
where the flower was, then lens-blur the background and superimpose the
flower back. Results were just about perfect.
I would definitely try green screen before this projection technology.
For me, a regular painted background is preferable to either of them.
Shop around. I found a good quality 10'x20' on sale for $50.00
Or use out of doors locations where you can throw the background
pleasingly out of focus.
