Doing a quick web search DOES show a few different "chroma key spray
paints", but not by any recognizable brands!!! The only ones that
seemed semi-legit were for touch-up. It's been a while since I've
bought any, but I seem to remember most actual chroma key paints being
about $50 a gallon.
Also, since I'm sure money is a concern for Tech Geek being at a
school, there are a couple of ways to work on lighting the thing,
inexpensively. The key, of course, to good chroma keying is bright,
even lighting.
If you've already got some kind of lighting grid, make sure the light
is even as hot spots (or dark spots) can play havoc on keying. Try to
separate your subject from the background as much as possible to
eliminate shadows on the background which will cause the strange color
haloing that was mentioned earlier.
If you're just using room lights for your lighting then a cheap way to
help with the chroma key (but will make some people here cringe, I'm
sure) is to pick up some flourescent work lights (as bright as you can
get) and line the top and the bottom (if you can keep them out of
frame) of the wall with them.
And I'm assuming those who say that keying is no longer used outside of
weather forecasting in television haven't watched a lot of local
television advertising (how often do you still see a used car dealer
keyed in over his dealership???)
Oh well!
