If you use a colored card board, you can just lean it on a book.

Yea just put something behind, but be mindful of the shadow and light.
For example, if you get it diagonally, you might get a small ray of light on top, and a bit of shadow too… And since the blue/green has to be as pure as possible, you better attach it the closest possible.

no no im asking what is the point…how is it done if a fig does a flip what do you attach him to? the bluescreen? do you just make sure he is in the same spot and where he was standing?

For the effect you describe, masking would be better- Egoless posted an excellent tutorial once on how to achieve this with Flash but I don’t know the link.

Myself, for that effect, I prefer to use one of those clear sticks Lego provides and then ‘remove’ it with Painter5 in post prod.

Bluescreening is most often used to combine a foreground with a background that would otherwise be too difficult to achieve. As an example I will use the spaceship scene near the end of my film METRO. I could have used a dark background and added stars in post prod (which is what i did in Midnight Ride). Or I could have printed off a still shot of a starfield and used that as the background. Or I could have used dark cardboard with holes punched in it and backlit to provide stars.
But I wanted to have the stars moving behind the starship so I chose to bluescreen. It’s not easy and lighting is essential, but if done right the results can be spectacular- hope that helps :)

:) if you want to do it the way that works best for me use something thats the same color as your background to hold up whatever your using. In the star wars movies (old ones) they held the models up with sticks wraped with something that was the same color as the background. TIP: whatever angle your shooting at try and point the stick or whatevers holding it up in the opposite direction, totally out of view if possible)
