Would it not seem appropriate for Kodak (or someone) to release a new slide projector/ viewing system? Is it already in the works and I just don't know about it? Is the fate of all (color?) film to be scanned to digital and forgotten in a box? .
There are so many old slide projectors out there, which work perfectly fine and available for almost nothing, along with the requisite trays, that I can’t imagine there would be a legitimate market for new projection systems.
The supply of already existent projectors is never going to be exhausted, and again, they work fine.
Screens, on the other hand, you’ll be needing a newly manufactured screen to do the slides justice, as the reflective elements generally degrade over time. Older ones are usable, and much better than a white wall, but a good screen matters.
But yes, even though slides can be enjoyed on a light box, or scanned with a scanner, or “scanned” with a digital camera, or used to create an internegative to print “the old way”, they are meant to be projected, color balances of the dyes are selected in order to be used in conjunction with a projector bulb of a compatible color temperature so that the colors in the projected image are “right”. Not that anyone cares that much these days.
Digitize them then move sliders around on the computer to get some kind of colors and let the program algorithm do what it thinks should be done to the color balance and you get some kind of an image you can post on the web, giving someone else an opportunity to opine that emulsion “x” is too green, or too red, or some such.
Transparencies an odd niche these days. I will scan mine and project the good ones as well. But, honestly, people who shoot transparency film and never project it, that seems like an expensive way to miss the boat. If you want or need color, and you are never going to set up a projector and a decent screen, just shoot C41 or digital. Seems to me. But, if someone enjoys shooting it and scanning it, it keeps it viable a while longer for everyone else, so that’s great.
