I started to digitize my old 35mm color negatives ( I duplicate them on a DSLR in DNG format). But I havn't found out yet how to convert them into positives...Is there a PP software that can handle that?
I use an older (bought it several years ago) Minolta Dimage scanner made just for slides and negatives. Software that came with that dies the negative-to-positive conversion

Assuming you have captured the reversed images, get a copy of VueScan and convert the negatives. Also, many editors, for example, PSE or Photoshop should have image inverters built in. CNTRL-I ?
Invert and color correct with the tone curve tools in Photoshop or Lightroom. Once you get it right for a particular film stock, save a preset!
Scanners with color neg conversion software are much easier to use.
Every brand, type, speed, age, and emulsion number of color negative film is different! Then you throw the color temperature of the light in each scene into the equation. The result is a tedious conversion process.

You can copy Color slides, B&W negatives or B&W prints with a camera. I've done it even for 4x5" films. But do yourself a big favor and get a scanner for color negatives or you will go insane trying to remove the orange-red mask manually. The software with a scanner can do that easily. Say a model Epson Perfection V5xx to V8xx Photo. Have fun.

I have used two methods...(1) Canon Scanner...with built-in film type setting...Photoshop editing...,and (2) copy with Nikon camera using Bowens slide copier.... Do White balance using piece of blank negative film ...edit in Photoshop....and print away...

If you get a scanner with the lighted top you can scan a positive image and not have to deal with conversion.

Have you tried a curve setting? Simply reverse the curve and see if that helps. I think it might but not sure.

Thank you all for your feedback. I probably did not express myself properly. I already digitized the negs by duplicating them with a DSLR. I have now DNG files which I need to invert and I thought there must be a piece of s/w to do that. I only have a few rolls of color negs from the past which would not justify acquiring a scanner. I'll check with viewscan next.

Scanners are slow, but I advise people to scan 35mm film at the maximum optical resolution anyway. You’ll need it for printing 8x10 and larger.
Open your image editor's graphic channel mixer. Take the RGB graph and flip it around. Then make adjustments to the individual color channels (R, G and B) to adjust the color tones and remove the bluish cast - a little difficult to get right at first, but after a few times it becomes increasingly easy.
Changed my mind about replying. I found more information. Found YouTube videos showing and explaining rook3c4's method.

You've copied color negatives that way and used only photoshop. How? That is a lot of balance from balanced white! A color negative does not really even produce a true RGB image (file). Yes, using an optical slide copier is another way to copy film other than a light box or scanner. But again sounds like trouble for color negatives. I've certainly never gotten good color from color negatives other than by Scanner. This might be the one or two cases where in-camera JPEG is better than RAW since you can set an applied WB. The colored mask is probably well beyond ACR! I'm not the only one suggesting to use a scanner.

Some while since the last time I did Col' Neg conversions, but seem to remember setting a Pre' white balance with piece of blank (processed) film in the negative stage, before exposing the negatives to be copied, onto a Digital camera. The digital images were then edited in Photoshop using whatever tools necessary to obtain a good print.
If you say it cannot be done, then I will not bother doing any more.
