When I became involved in photography in the 1940s, Kodak was King! They made fine cameras, and some lenses that had all the quality that most LF photographers need, even after 80+ years. I also relied on their many publications, from the information sheets that came with film to the many publications. How the mighty has fallen! Kodak provided reliable processing by mail for Kodachrome from almost anywhere on Earth during a Navy career. The last time I looked, those slides from so long ago are still in good condition while some other brands are now useless. Kodak was a leader in B&W film. Their Recording Film 2475 could be rated from 1000 to 4000 ASA, while Tri-X was normally rated at 400. This let me shoot indoor sports with a Summicron at f/2 at twice the shutter speed instead of the less sharp Canon f/1.4. Kodak also produced the fine High Speed Infrared 4143 sheet film. Kodak's Technical Pan film was a very sharp film. Although designed as a high contrast film, it could be developed for near normal negatives that permitted large sharp enlargements. The sheet version could be developed in Solar developer with a reversing exposure during development for solarized prints, as below. This nude was photographed against a black background, which reversed to a more pleasing grey in development.
