Photographs of the corneal endothelium are taken usually with special purpose cameras or by using the Holden-Zantos technique with a conventional photo slitlamp. The latter method requires the camera back to be mounted on the photo slitlamp eyepiece and the resulting slide to be magnified by being rephotographed with a slide copier. This report describes another way of obtaining the requisite magnification using a teleconverter placed before the camera back mounted in its usual position and special darkroom techniques exploiting the properties of Kodak Technical Pan, a fine grain, variable contrast film.
