Polaroid Lifts
The photographs below show how i have lifted the image from a Polaroid 600 film. This technique is simple when you get the hang of it. I just have to reiterate that when handling these films you are coming into contact with toxic chemicals and you should refrain from putting your hands near your face or coming into contact with food as they can make you quite poorly. Firstly i would recommend lifting a Polaroid film as soon after you have taken it as the developing paste is easier to remove, the above images are a few days old and the developer had set making it next to impossible to remove. I dont think it makes the image any less attractive though. The tools you will need are watercolour paper, the heavier the better, watercolour brushes, i use three, two thick and one thin for refining the image. A sharp scalpel and a pair of scissors, a dish, either a developing dish or one out of your cupboard just wash it after use and a kettle as you will need plenty of boiling water. A Polaroid film is made up of the following, Three layers sensitive to different colours of light, with a developer layer under each layer, there is a reagent which sits just above the light sensitive layers and just below the image layer.The reagent material is all collected in a blob at the border of the plastic film sheet, away from the light-sensitive material. This keeps the film from developing before it has been exposed. After you snap the picture, the film sheet passes out of the camera, through a pair of rollers. The rollers spread the reagent material out into the middle of the film sheet, just like a rolling pin spreading out dough. When the reagent is spread in between the image layer and the light-sensitive layers, it reacts with the other chemical layers in the film. The acid layer in the film reacts with the alkali and opacifiers in the reagent, making the opacifiers become clear. This is what finally makes the image visible. The timing layer slows the reagent down on its path to the acid layer, giving the film time to develop before it is exposed to light. One of the coolest things about instant photography, watching the image slowly come together, is caused by this final chemical reaction. The image is already fully developed underneath, but the opacifiers clearing up creates the illusion that it is forming right before your eyes.
