Instant photographs from Polaroid cameras have the clear advantage over former media that the photograph can be seen within seconds. But Polaroid film also lends itself to a wide range of manipulations. Many of these need no more than the camera, the film, and a blunt-ended instrument such as a pen.
With Polaroid image film, for instance, as soon the photograph is ejected from the camera the dyes inside the photograph 'sandwich' can be squeezed colse to before they set. This will create bizarre patterns which can, with practice, be controlled quite precisely. When the photograph appears fully the results are amazing,
Polaroid Printer
A Polaroid back fitted to a approved camera offers someone else technique, which is known as image transfer. Once the film has been exposed, it is pulled straight through a pair of rollers built into the back. These squeeze and spread the chemicals that make the film. Development of a approved print usually takes 90 seconds. But as soon as the film emerges it can be peeled off its backing sheet and this sheet pressed face downward onto a piece of paper wholly dampened with water, and left for the remainder of the Development time. This transfers the image to the paper, after which the former material is discarded. The effect has none of the smoothness of a approved Polaroid print. The effect is raw and blurred, but often stunning.
Apart from Polaroid cameras and backs there is also the Polaroid transparency printer, which makes instant prints from approved slides. These can be manipulated in the same way as those from a Polaroid back.
These are only some of the techniques. There are many others, along with immersing the film in boiling water and scratching the emulsion.
