A Hand-held Otophotographic-System with Automatic Exposure Control
E. Müller-Hermann, G. Münker · Endoscopy · 1982
Correct lighting and exposure of color photographs was often the main problem in otophotography. The photographic equipment used for this area was complicated or troublesome to handle. To facilitate handling and to overcome the numerous exposure problems in otophotography, a new otophotography system (OPS) with TTL-computer flash has been developed.
