Slide projection
From the end of the 1920s, the first projection equipment appeared on the market for 35mm film slides, but it was not until after the war that colour slides emerged.
Slide projection really took off after the 1960s. Photography on this basis was cheaper than colour-printing from a film negative, storing slides in boxes was quite practical, and slide shows could be rather pleasant occasions…
Thus, a number of slide projectors appeared on the market for domestic use, and the professionals were also partial to these accessories, which were more convenient for printing applications.
Some specialised in “slide shows” and developed their techniques, working with fade-ins and fade-outs using several projectors. Everyone can still remember the kind of shows staged at the1964 Swiss National Exhibition…
With the advent of video and digital equipment, slide projectors began to lose ground and could well soon become collectors’ items, albeit extremely interesting in their diversity, as almost every brand had its projector, often linked with a very specific slide-viewer.
