3.0 Camera and Equipment

The Zeiss FF4 series and the Topcon TRC-50EX (used at the 35° setting) or similar model are suitable cameras for the study. Cameras other than these may be substituted upon approval of the UW-FPRC. Approval may be obtained by submitting two sets of color photographs and accompanying fluorescein angiograms, taken according to procedure, together with a letter requesting camera substitution, to the Fundus Photograph Reading Center, 610 N. Walnut Street, Room 438, Madison, WI 53705, Attention: Michael Neider. Photographer certification photographs may also be used for camera approval.

4.0 Film and Processing

For color photography, the recommended films are Kodachrome 25 or 64 Daylight film, processed by any authorized Kodalux Laboratory, or Professional Ektachrome 100 Daylight film, or its equivalent, preferably processed by a certified "Q-Lab" to ensure consistent quality. It is important that the processor correctly number the slide mounts to make slide sorting more accurate and easier. Kodak T-Max or Ilford 400 speed film are recommended for angiography. The film may be processed by the clinic staff or at a local processing laboratory. The use of Kodak D-11 developer is recommended. Development times will vary with developer concentration, temperature and camera flash setting. Any processing procedure which yields good quality negatives may be used. Proper care should be taken to adequately fix the film to insure archival image stability.
