Polaroid (polarizer) Polaroid (polarizer) Polaroid is a type of synthetic plastic sheet which is used as a polarizer or polarizing filter. A trademark of the Polaroid Corporation, the term has since entered common use. The original material, patented in 1929 and further developed in 1932 by Edwin H. Land, consists of many microscopic crystals of iodoquinine sulphate (herapathite) embedded in a transparent nitrocellulose polymer film. The needle-like crystals are aligned during manufacture of the film by stretching or by applying electric or magnetic fields. With the crystals aligned, the sheet is dichroic: it tends to absorb light which is polarized parallel to
Polaroid transfer and quickly pull the film apart, not letting the two sides (the picture and the negative) touch. Put the pulled apart negative face down on paper (or other material). Place pressure over negative and let sit for about 20 minutes. Then pour hot water over each side of the negative/paper sandwich. Gently peel the negative from the paper. Allow transfer to dry, face up. Slide printers allow you to make Polaroid transfers from previously-taken slides or negatives.
