more on shadow idea
- Strobe light freezes shadows in place
- Phosphorescent screen(aka glow in the dark paper**) hangs on wall
- blue leds can be used to add details to shadow but not necessary; (this(blue) wavelength of light is best to show immediate results on the paper as seen in the video I showed in class)
So the paper can be purchased anywhere.
**In simpler terms, phosphorescence is a process in which energy absorbed by a substance is released relatively slowly in the form of light. This is the mechanism used for 'glow in the dark' materials which are 'charged' by exposure to light. Unlike the relatively swift reactions in a common fluorescent tube, phosphorescent materials used for these materials absorb the energy and 'store' it for a longer time as the subatomic reactions required to re-emit the light occur less often. (wikipedia)
But instead of the glow in the dark nature being of most significance it is the shadow revealed that is the true artform.
