Yeah,
        I thought about that too, having taken those color-blind tests as a 
kid.  What about people who may be able to see those bits on the original photo 
though.  I was thinking of some sort of clearcoat which when the original photo 
is viewed can't be seen, but when scanned a part of the coating would be 
encoded.  I don't know just brainstormin'
