AN AMATEUR'S APPROACH TO PHOTOMICROGRAPHY MICHAEL

Definition PIIOTOMICROGRAPHY

is photography of an object as enlarged under

the microscope. Introduction This is not intended to be an authoritative article, but an account of the results of experimentation by an amateur in this fascinating field. It is surprisingly easy to obtain an adequate photomicrograph even with simple apparatus. Apparatus A rather old monocular microscope was used at first, but this was later replaced by a more modern binocular model. A 100W. household bulb provided the source of illumination the light being reflected from the plane mirror through a substage condenser. The camera was a 35mm. iris shutter model with speeds varying from 1 /300 to 1 second. Setting up the apparatus Some method had to be found by which the camera could be firmly suspended over the eye-piece of the microscope and yet be easily and quickly swung aside when not in use. Since the subject matter was mainly living organisms, manipulation of the camera over a monocular eye-piece had to be slick in order to catch the organisms, which were rarely obliging ! The advantages of a binocular eye-piece were therefore apparent, as the camera could be arranged over one eye-piece while the operator used the other. The camera was attached, by a boss, to the pole of an upturned retort stand, the base of which was securely clamped between two spars of wood {diagram). This clamp could be relaxed by a butterfly nut to allow the whole camera assembly to be slid side-ways out of the way. The whole assembly was then secured to the walls by chocks. By this simple apparatus it was possible to move the camera in any plane rcquired quickly and smoothly.
