ok so i made a cam with 2 pinholes, one covered in red, one covered in cyan---objects that are close to the camera can stand out in 3D when you wear old time red/cyan 3D glasses
cyan-shine, bkspicture, elede, herbert-4 & stouf.
Brilliant!! I only have a red and a green filter to look through, and with half being cyan, it only almost works. I need a blue filter.
