Visual Thought Keywords during Exposure: Concentration on producing visible spots and light

Comments: This experiment leads to weird chemical reactions. Polaroid had to be pulled manually through the rollers. Next image got lost, last image [2] on film turns out with light spots without being exposed to any light and pulled out normally of the polaroid back.
