Light the Recorder

Synopsis
Discusses the development of black-and-white photography, and explains the three-layer principle of the colour process. Many printing processes also rely on photochemistry, the diazo process (dye line machine) and the photopolymer plate (offset lithography) are demonstrated. Professor Heller explains the basis of photochromic compounds - the subject of his own research. Finally looks at a machine which finds uses for three of the different imaging systems seen in the programme.

Notes
NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
