Subject: Re: [Puptcrit] Question about green Lycra suits for green-screenwork


Any recommendations for a source for the correct color and purity of the
green Lycra?.

Below is some speculative thinking about the issue of chroma-keying puppeteers;

It has been years since I looked into chroma-keying, but I understand that
there have been significant advances in this field over the last few years.
Perhaps current programs will be more tollerant of variations in the hue of
the fabric.

Another advancement I've read about is the use of retro-reflective surfaces.
This is the type of stuff they put on street signs so that they reflect your
car's headlights.  In chroma-keying you place the light source near the
camera lens, and in the application I saw, it was actually a ring of LED's
around the lense.  Basically what this does is illumnate the
retro-reflective fabric without putting very much green light on the subject
of the video.  I suspect it would also help remove the issue of wrinkles,
but I've never actually tried such a system.
