I've been thinking about using C41 print film after my slide film is used up. However, my main use of slides is projection, and projecting a negative film leaves a result that is, well, useless.

Yes, negative film can be scanned and converted on the same film scanner used for slides, but that means eventually having to use a digital projector. I see no gain there -- nothing more than adding extra steps.

So...does anyone know if some type of converter was made, letting you project negative film and getting the colors of positive film? Just ruminating, folks.

Kodak Vericolor slide film SO 279. I still have 1 roll left. It's doubtful anything like it exists now.

Never heard of one. You might look into having slides made from your negatives. Check with a professional color lab in your area. They should be able to handle it or will know a lab that does.

I can do the 35mm scans myself. I hae two film slide scanners (Minolta and Nikon), and I know that process well. I just wondered if anyone made a projection solution. Seems to me it could be unwieldy.

I think I might have been unclear. I was looking for a way to project a negative, but get a positive/slide coloration.

I'm aware of that, but do not believe any such animal exists. Kodak developed SO 279 to address that very issue.

Why not just use your image editor to do this. Process the first image scan, using the curves adjustment (to flip from negative to positive, and to adjust the blue channel). Record the process as a custom action and automatically batch process all following scans with this action.

The OP does not want a digital file.

Not sure how it is done but I saw a Youtube Video using Lightroom to convert negatives to Pictures. If you use lightroom maybe someone knows the proceedure. Good Luck!!

Process the negative and make a print, scan it and print to transparency material?

Strange film, but beautiful images.

I remember I used to get negatives, prints AND slides from color negative film from DALE Labs in Hollywood, FL (800-327-1776). Maybe they still offer that service. Give them a call. Top-class customer service. But be advised- the nature of the process is such that your slide, which is a "print" of your negative, will not be as sharp as it would be if it were shot on slide film itself, which is a 1st-generation image.

Yes. Fuji used to make a device, perhaps called "Fujix", that previewed negatives as positives on a small video screen, so that professional photographers could show images to clients without having to make proofs. They were around on the 1990s, you could probably get one for next to nothing now. However it is not a projector. Perhaps it has an output that you could hook up to an RGB projector. Resolution is quite low however.

In fact, check this out for reference:

Mickley,

Here's an approach that should give you a live positive on your computer, which you should be able to then project.

Position your negative on a light box.

Position your camera or camcorder over the negative and focus on the negative.

Tether your camera or camcorder to your computer and use some software to view it live on your computer.

Then, use the accessibility settings on your computer to invert the colors.

This will give you a live positive image of your negative, but it will not be color corrected.

I've not used Vericolor III, or Portra, but I copied several hundred negatives on SO 279 for a friend about 30 years ago, and it produced great slides for projection. It wasn't daylight balanced and filtration was a bit tricky. I don't recall what I used for lighting or filtration, but the colors looked pretty natural. Fortunately, we don't have to go through all that hassle nowadays.
