I own an operate a small Pro Lab in Sydney Australia that is dedicated to analogue processes, I Have always had a passion for some of the more obscure analogue materials such as Polaroids now discontinued Polachrome 35mm, SX-70 and 665. Kodaks now Discontinued EIR colour infra red, Technical Pan Film and Royal 25, Agfa's ultra 50, Apx 25 or that gem of a transperancy film RS 1000. Then theres glass plates!!!! oh the list goes on. While I stock a large range of these materials in deep freeze If there are any materials any of you may seek, I am aware of other great sources for rare film stocks and would be more than happy to assist you in locating the materials you look for.
