Prof. Crane you mentioned in class that old movies have this fringing effect, but not because of poor alpha processing. What exactly was the reason?

I am curious why the whole background seems to be darker when there is no fringing.
In class, I remember Professor Crane said fringing only affects the surrounding of the ball but did not mention it also affects the whole background?
Thanks

@xTheBHox Lots of possible reasons; one is that if you're using a green screen and you're too close to the screen itself, the green light will bounce onto the subject. Now when you go to do compositing, you get a halo.

@siliangl I'd ignore this slight darkening; this is just something going on with the slides (or the way they were uploaded to the web).
