The fact that i shoot 90% black and white 9% Kodachrome and 1% E6 might have something to do with that." That's to be expected. ICE works by measuring transmission through the film in the IR region. The dyes in colour slide films are transparent at the IR wavelengths used, and the system assumes that anything it detects is dirt. Of course B&W emulsions *aren't* transparent at IR, and so you wouldn't expect ICE to work on B&W negs. When set up correctly such systems work very well. When I was employed at the BBC's R&D labs, designing CCD telecine equipment, we had this working in real time on 16mm and 35mm movie film in 1978, and it made a huge improvement. - -- David Morton dmorton@journalist.co.uk Wapingapo fahali wawili, ziumiazo ni nyasi
