Additive Light (and subtractive sort of)
So we have been taking last semester’s work down and I was curious to see if the lights I had made and put RGB filters on would add up to white light when all shone onto a white board, which they do, see photograph1.
Then I put my finger in the way and found you get three different shadows made of the secondary mixture of the two you have not obscured, photograph 2
Next photo slightly more complex shadow of a metal fixing plate and notice that where all the lights are obscured the shadow is black
Next photo "Saturday Night Fever" starring Jenjens gluegun men.
No photo but a sample of my butterflies looked very pretty if a touch twee, I can see playing with this for a week or two
