ok folks before I get luaghed at anymore :) he he

I will explain the reason for my madness. It has to do with trying to composite 3d character in real world and have it look believable.

Attched is image of frame clip I saw on making of starwars Ep.2

In everyscene where there was a 3d character composited the production guy held up a silver ball and a model of character.

The question is. What is the ball for? I could think of only two possible things each not perfect but please include your ideas for what you think the ball is for.

The Theory is if the ball was more solid perhaps all the lights on the location would be recorded on that ball so that if I used a still frame of the guy holding up the ball you could use the ball light controls like poser uses to match your 3d characters highlights then match with the ball from your real environment thus making a great composite.

The other theory is the sphere image reflection is captured and used on the character for a realistic reflection map. But that has flaws because the production guy could be scene in the reflection.

Sooo...although I am venturing into a non poser topic. What is the reflection ball for?

I believe my theorys are close in accuracy but stil they arent perfect.
