History |
This film box was owned by Mississauga-based photographer John Hammill. Gevaert Ltd. was founded in 1894 when Lieven Gevaert began producing photographic printing papers on Anselmo Street in Antwerp, Belgium. A year later, in 1895, Gevaert Limited was established as a public company, and in the same year, a factory was constructed near Mortsel to manufacture films, photographic glass plates, and printing papers. In July 1964, Agfa and Gevaert merged. Initially, both companies continued to produce color film and printing paper under their respective brand names, but by the late 1960s, products were labeled "Agfa-Gevaert." In 1981, Bayer, which previously held a 50% stake in Agfa-Gevaert, became the sole owner. Diapositives, also known as lantern slides, slides, or transparencies, differ from paper prints in that they are typically viewed by projection. They consist of a silver image on a glass plate or a clear/translucent film base. Diapositives can capture approximately 400 separate tones, compared to about 250 tones for paper prints. |
