Blue Screen/Wall Trouble

JPuffy001 wrote on 9/9/2008, 2:49 PM

So instead of buying a blue screen (because I couldn't afford one) I painted a wall in my garage blue (it's 12X8 feet). For the most part it works well, the only problem is that when a person stands in front of it, their shadow that they cast causes marks to show up during the editing process. Is there a way to light the scene without casting a shadow or is there a way to get rid of the shadow? Thanks in advance!

to avoid the shadow you need to light the blue wall up close, intense and evenly. then your problem will be the reflected blue cast from the wall to fix that you need to have a key light from above and behind your subject to wash out the blue.

What you can also do is buy a Blue Queen or King size bed sheet; make a 12x8 frame out of 1x2's; stretch the sheet tight and staple-gun the sheet to the frame.

Then evenly backlight the sheet with florecent lights,

Whichever way you do it .. the background for a chromakey shot *must* be evenly lit .. and .. you need to have lights that are *only* used to light the background.

Also .. do not put your subject close to the wall when you shoot. That will help to reduce or eliminate the subjects shadow falling on the wall, and the effect of the wall color reflecting onto your subject's edges.
