The protozoan Paramecium by phase contrast
by James Evarts, US
image will take a minute or so to download but worth it!)
This magnificent image of Paramecium caudatum shows many of the protozoan's cellular structures. The image was taken by James Evarts.
The photomicrograph was taken using my regular setup which includes a Leitz Ortholux microscope, 16x phase contrast objective,10x ocular, and electronic flash unit with a dark green filter attached. I developed the film (Tmax 100ASA) in my home darkroom and used RC paper for the print that I scanned to send by Email.The length of the living Paramecium was approximately 200 microns.
The flash unit was a Nikon SB-E mounted on a machined metal block that James prepared in his own workshop. The flash unit is on a swivel mount with pin stop to ensure the flash unit is perfectly centred under the microscope condenser for photography, but can be easily swung out of the way for visual work. (The unit was discussed and illustrated in the magazine Industrial Photography, 1991, October, volume 40, no.10, p.18 and p.40).
Comments to James Evarts welcomed.
