Roger recalls only too well working late into the night in the early 1970s, duplicating slides for an AV presentation. By midnight he was just finishing but he was dog-tired; so tired that he knocked one of the exposed cassettes on the floor.

We do not know how important this is in assisting stiffness and loading.<\/p><p>Some Robot cassettes had a velvet light-trap but the lips of the trap were pushed apart when the camera back was closed. This allowed a tighter trap when it was closed, allowing better light sealing, and greatly reduced the risk of scratching when it was open.<\/p><\/td><\/tr><\/tbody><\/table><p>A few manufacturers have offered 250-exposure models, or 250-exposure backs, with corresponding cassettes: Leica was the earliest of the major systems to do this, but Nikon and others have done the same. The cassettes in question take about 10 metres (33 feet) of film.<\/p><p>Most other cassettes are even rarer, such as the extra-small cassette for Tessinas and one or two from the 1920s and very early 1930s before cassettes were standardized: in those days, every manufacturer made them to his own design.<\/p><p>\u00a0<\/p><p>\u00a0<\/p><h6>cassette-to-cassette<\/h6><p>\u00a0<\/p><table border=\"0\" width=\"100%\" cellspacing=\"0\" cellpadding=\"2\"><tbody><tr><td valign=\"TOP\" width=\"50%\"><p>A few cameras allow you to work cassette-to-cassette, whether dedicated (e.g. original Contax) or with standard velvet-lip cassettes (e.g. Exakta). This offers several advantages including the loss of only a couple of frames of exposed film if the back is opened by mistake, and minimal film loss if you want to change films in mid-roll. Loading is however slower and less convenient. Another drawback, which had not occurred to us until we tried it, is that you can end up with the film in a different cassette. Here, for example, the camera is loaded with Ilford Delta 100 (Exaktas work &#8216;backwards&#8217;, remember) but the film could end up in an old Acupan cassette. Devotees of Exaktas may be interested in the paid\u00a0review.<\/p><\/td><td valign=\"TOP\" width=\"50%\"><p align=\"CENTER\">\u00a0<\/p><p align=\"CENTER\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-227\" src=\"https:\/\/www.rogerandfrances.com\/wp-content\/uploads\/2021\/11\/choosing-reloadable-cassettes15.jpg\" alt=\"\" width=\"345\" height=\"250\" srcset=\"https:\/\/www.rogerandfrances.com\/wp-content\/uploads\/2021\/11\/choosing-reloadable-cassettes15.jpg 345w, https:\/\/www.rogerandfrances.com\/wp-content\/uploads\/2021\/11\/choosing-reloadable-cassettes15-300x217.jpg 300w\" sizes=\"(max-width: 345px) 100vw, 345px\" \/><\/p><p align=\"CENTER\">\u00a0<\/p><\/td><\/tr><\/tbody><\/table><h6>\u00a0<\/h6><h6>working without cassettes<\/h6><p>\u00a0<\/p><p>With cameras where you do not have suitable cassettes, it is often possible to improvise some form of feed cassette (usually based on the centre spool of a standard modern cassette) and load and unload the camera in the darkroom.
