Thinking of doing some experiments with 35mm high-contrast B&W or color transparencies.
Source material would be digital files, similar resolution to typical consumer DSLR or iPhone image frames (4K pixels x 3K pixels, for example), with output to real film transparencies (or even B&W negative film).
Casual googling brings up some film recorder service bureaus that offer such services for maybe $5 per slide plus handling fee, with turnaround times from a day or two up to perhaps a week or longer.
Anyone have experience with any such vendor(s)?
I suppose that an alternative could be had by rigging up my Nikon F2 SLR with some real color transparency film or B&W negative film, and take macro photos of my iPhone screen in a dark room, then find a place to develop the film. I don’t actually need these to be mounted. Figuring out proper exposure might be a bit painful, as I’ve been spoiled by digital SLRs.
