Both Rectigraph and Photostat machines consisted of an outsized camera that photographed documents or papers and exposed a picture directly onto rolls of hypersensitized photographic material that were concerning 350 feet (110 m) long. A prism was placed ahead of the lens to reverse the image. once a 10-second exposure, the paper was directed to developing and fixing baths, then either air- or machine-dried. The result was a negative print, that took concerning 2 minutes in total to provide, that may successively be photographed to create any variety of positive prints.
The photographic prints made by such machines area unit normally stated as "photostats". The verbs "photostat", "photostatted", and "photostatting" check with creating copies on such a machine within the same means that the proprietary name "Xerox" was later accustomed check with any copy created by means that of static photocopying. people who operated these machines were referred to as photostat operators.
It was the expense and inconvenience of photostats that drove city Carlson to review electrophotography. within the mid-1940s Carlson sold-out the rights to his invention – that became referred to as picture taking – to the Haloid Company and photostatting before long sank
