Shoestring

[StokieSam]

Hi everybody, how's about this for an abstruse first post. Many, mnay years ago, I was taking a course with the Open University here in the UK. The course was on imaging and image processing, so included all kinds of stuff about Fourier Transforms and other mathematical insanity, but to add some practical experience and excitement, we were asked to produce a hologram, using a low power laser, a simple optical bench and a very basic 35mm 'box' camera (no lens, just a shutter). The film was supplied in a normal cassette and we were provided with the chemicals and instructions to process it in the cassette. This involved lots of twiddling and shaking in a jug of developer, then rinsing then fixer, etc. This worked OK for the 5 or 10 exposure length of film we were given. Remember that this is distance learning and everything was supplied in a big cardboard box and they obviously couldn't make any assumptions about what people might have other than ordinary household items. This thread brought back many memories.
