This chapter revisits a technology from your youth that s being reinvigorated because of scanners. Instant images from Polaroid cameras used to be sort of one-of-a-kind objects that were difficult and costly to reproduce. Scanners have solved that problem more effectively than anyone could have imagined a decade ago. Today Polaroid cameras are inexpensive streamlined and simple to use. The emergence of scanners gives you the ability to enhance copy and share your instant images with the world. Even more exciting Polaroid has even developed its own mini-photographic scanner Webster to be used with its instant-imaging cameras and film products. How Does Instant Imaging Work All instant imaging is based on a technology of treating paper inside the camera with layers of light-sensitive chemicals that you activate when a picture is taken. As you ll notice the finished Polaroid pictures are thicker than those developed by other processes. When you take your photo the camera quickly spreads a reactive layer of chemical across the paper on which your finished picture appears. This first chemical layer called the timing layer disappears after 30 seconds. Behind the timing layer is an acid that reacts to the unexposed and exposed portions of the photo to create the finished color image.
