A microform data acquisition processing and storage system in which data is fed from a computer, tape or cards to a cathode ray tube from whence an image produced on the tube is projected onto a photographic film or alternatively by means of an optical switching device an image of a document located on a document platen within the apparatus can be projected on to the same film without changing the film; the cathode ray tube is provided with a coating having a spectral peak between 500 and 600 nm so as to match the spectral peak of the image on the platen.
