ABSTRACT
Surely they would welcome the liberation from external power sources, the small size and light weight of a piece of film, its flexibility, allowing it to be wrapped on a compact spool, and the fact that it can sit for months, even years, on a shelf and be ready for use instantaneously. They would point out that the sensitive material of this very inexpensive product is itself converted to the recorded image by a relatively simple chemi cal treatment requiring, in its basic form, no complex auxiliary equipment. They would marvel that it can be made sensitive to select spectral ranges from the ultraviolet well into the infrared and to high energy particles or radiation, and over the remarkable extent to which it can be made to yield a true (or, if desired, false) color rendition of an original, or a black-and-white image with archival stability. They would extoll the superior image quality of this new product, emphasizing its extremely high information packing density, its sharpness, its uniformity, its low level background noise, and its freedom from defects.
