Wiper was made in 1977 at the Birmingham Filmmakers Co-operative. At the time they had very few resources other than enthusiasm and a 16mm Bell & Howell camera on loan. The only publicly accessible resource of the type required to produce the frame by frame manipulation in "Wiper", was the optical printer at the London Filmmakers Co-operative (LFMC). The production required the filming of the original footage and subsequent re-photography to produce, in the intervention and restructuring of the frame order down to single frames. Photography took place on the outskirts of Birmingham using an electric drive Bolex camera borrowed from the Arts Council in Piccadilly. The subsequent re-photography took place at LFMC using the optical printer. The time manipulations in Wiper were made by rephotographing frames from the original footage in the new order required. Choice of frames could only be done by estimation by eye, and considerable testing was done to get the smoothest effect possible. This re-photography took several weeks, travelling to London each weekend. Laboratory processing was out of the question for tests, the short lengths of tests being difficult to deal with on machines designed for continuous operation, but also the time taken to review test material and test again would have extended the entire procedure of testing and analysing results for months. Consequently, weekly travel to London was with an accompanying mini-laboratory of Ukrainian made 16mm processing tanks, bottles of developer and fixer, and a borrowed hair dryer so that tests could be processed immediately and further tests carried out.
