I don't want to sound stupid, but I saw a thread on another forum about copying digital onto slide film. I'm just perplexed as to why anyone would want to do this. Is it (as I suspect) for 'future proof' archival purposes, or for some other reason.

For projection
For a print production where a tranie is required
For archival purposes
For duplication and dissemination

I don't do it with film, but I do my power point presentations to slide film every once in a while, when I can't use my laptop and a LCD projector, so I can show the presentation with a slide projector, at the store I used to work at, we did it for quite a few people, many of them were done because artist submitting to certain contests needed slides because the contest would not accept digital images and they took images with their digital cameras, been a pretty common practice for many years now.

This thread probably belongs in the grey area sub-forum.

I have had my lab do this when I need patterns or words for projection on to a subject, as part of a photographic composition.

Since there's been interest in film output for digital internegs for alt process printing, I'll move this to the Gray Area.

I have probably done this for about 8 years. That is because all my work in multiformat sizes (35mm, 2 1/4" Sq, 6 x 7 cm, and 4" x 5") were all taken on transparency material. The final photos have been prepared and printed on Chromira and Light Jet machines for a long time. However, for particiaption in Art shows the work had to be juried from transparencies. So, my completed digital files in the various sizes were produced as analog transparencies for competition into these shows.

Yep, some people love to chase "gongs" in competitions with a slide category/division. I know one guy who works exclusively with digital cameras, does all the Photoshop manipulation ( and quite extensively at times ), gets a lab to burn the file onto slide then enters it into the slide division of a competition. This begs the question, is it ethical to enter a competition where the intent and spirit of the competition is to display your talent at taking images on slide film if you don't actually use slide film at any stage yourself? Over to the ethics commitee..........
