I assumed the more sophisticated (and more expensive) companies used a more professional method. I know little about film recorders and I'm sure what little I heard was connected to Polaroid film, but I've never had to find out detail about them. I've seen such a range of prices and I'm sure that one at the very lowest price range implied copying by the methods I want to try. As for why, I meet up from time to time with a few people who project 35mm slides, mostly of our local area as it was some years ago. As I took slides for decades and am starting to do so again, I have a large range to show, but I have a gap of many years where I've only had a digital camera. I'd like to get a number of them in film slide form to show them. I'm fully aware that digital projectors are coming down in price, but this isn't about new technology. It is a fairly pointless exercise in technological terms, but this is just for fun and the old projectors and slides are part of that atmosphere. You always hear about converting images the other way to digital format, but for the first time was asked about going the other way to film and that interested me. I'll give it a roll of film and see what is - or what isn't - possible.
