I'm trying to get some video work done in front of a green screen. I
have been very dis-satisfied with the price of the screens I've seen in
photography shops, so I decided to build my own. The fabric cost me
about $5 and I built the stand and all for under $50.
Here's the trouble. I can't seem to get a perfect key. Most of the
problem seems to stem from uneven lighting on the screen. The only way
I can light it evenly is from the front of the screen but then my body
casts a shadow on it. I could possibly light it from the back, but I
don't have enough room as the room I'm shooting this in is only 10 feet
square. I'd need another 10 foot to place a bright light behind the
screen and get even lighting. If I put the light beside or below the
screen, then the light is at an angle and doesn't evenly light the
screen.
Another problem I'm having. My camera is an older, cheaper digital-8
camera. It does not have a manual white-balance setting. So what
happens is when the camera shot is totally green, the auto-white
balance kicks in and desaturates the green. It is still green, but not
as much as it should be. Any ideas to prevent this (short of buying a
new camera?)
