title: An image reversal process for electron microscope film.
abstract: An improved technique has been developed to produce a positive image directly on some standard electron microscope films (Kodak 4489, SO 163, and Ilford Electron Microscope Film). This technique has been useful for processing micrographs of freeze-etched and shadowed specimens, and eliminates the need for producing positive image transparencies before printing.
