Experimental Polaroids

Shooting with expired films could give unsepected results, such as color shift, monochromatic pictures, solarization effects. In addition, the paste which carried the color pigments in integral sometimes did not cover the complete image, so the brown backing foil showed through. This could be caused by dried out paste or failing rolls in the camera, through which the picture was ejected from the camera and the paste was squeezed onto the foto from its pocket immediately after exposure. By applying pressure to the image surface, you could further manipulate colors.
