Why? Have you tried it, or just guessing?

For one, the slide projector has the perfect light source for your slides. If you have a quality screen to project them on, then you should get a darn good rendition. Also it would be fast. Load up your projector which holds a lot of slides (about 100 from memory), so this would be fast.

I know slide duplicators that do one slide at a time are useless, as are scanners if you have thousands of slides to copy. Also, if you are right, and the quality not perfect, you could always yank out the few pics you want to spend time with and use another method, or more likely, spend some time in PP to fix it up. I don't see any reason this method would hurt quality enough to matter.

Projection lenses are not of the best quality and even though they don't have very large aperture the aperture can't be stopped down and you will have problem having the entire slide in focus. I many projection lenses both flat and curve field and none I can have good focus of the entire slide.

Not sure why I can't get the entire slide in focus? IF, the slide looks good on the screen, I think my camera could take a pretty good picture of it. After all, it's just light reflected back to my camera?

If it looks as good or close to what is displayed on the screen, that's good enough for me. I'm not expecting it to look better than it did 40 years ago, although if I like the pic, I could always work on it in Affinity.

Have you actually tried this method. If so, was it on a quality, high reflective screen? 40 years ago I used to display them on a white wall, or white sheet. I remember them being quite nice.

this is what I use and a slide holder to keep the slide flat and a light table and a old enlarge

Several years ago I used a slide holder/scanner device that screwed onto my digital camera lens.
I used daylight for the background light and got acceptable results. I am just an amateur so acceptable to me might not be up to your higher and more critical standards. Has anyone used this method?

Nikon has a model

I am preparing to embark on a slide duplication project. I have many thousands of slides that I would like to duplicate digitally and am establishing a system to do this en masse with a Nikon D 800 recording the images. These slides (all slides) were originally intended to be viewed using a dedicated projector with a specific color incandescent light source. My question is how to best illuminate these slides -not using said incandescent light source - to obtain the best color match?

I used a 5500k LED shining on frosted plexiglass.

I've thought about setting up a slide projector, displaying slides on a quality movie/slide projector screen, setting up a tripod with my camera and a remote switch, and snapping away. My slide projector broke so I can't try it out. Has anyone tried that? I've done scanners, and cheap slide duplicators and they are slow and not so hot.

I tried that setup a few years ago but used a sheet of white poster board. It was just a test setup, seemed to wok well. Unfortunately we moved and the slide projector is in a box around the house somewhere.

What ever works for you, the number of slides does not matter!

I suppose a Bowens Illumitran or Magnum copier is out of the question. They are made for the job.

If you have 10,000 slides to copy it would seem to matter. I can see me sitting down with a beer, 140 slides in the carousel at a time, slide show on the projector, squeezing off a pic with my camera remote release when I saw a slide I like. Much, much better than doing one at a time on a scanner, or back light.

Yes, that's what I was thinking, except instead of white poster board, a nice high quality movie screen with embedded glass reflectors in it. Someone gave me one a long time ago, I think it would work well. Unfortunately, when I last fired up the projector to give this a try, it was broken.

It's the projection of the slide on the screen that you can't get the entire slide in focus.
