The High-Speed Photomicrography of Fresh-Water Protozoa

Paper presented at a Symposium on “Techniques in Applied Photography” organized by The Royal Photographic Society on 2-3 December 1965 in London.

Abstract

The Protozoa, together with some other groups of micro-organisms, present the still photomicro- grapher with special difficulties. The rapid movements of these organisms in the microscope field and their lowcontrast images have led workers in the past to produce records of stained, dead material almost exclusively. Electronic flash devices used in conjunction with contrast-increasing optical techniques now make it possible to make routine photo-micrographs, in colour if necessary, of events and structures not before recorded in the living animal. The paper describes the techniques and equipment used by the author in photographing freshwater species. Research carried out under the aegis of the Royal Society's committee on Scientific research in schools. The full text of this paper is published in The Photographic Journal, 106, 333 (1966).
