Cine Color intermediate film is made to obtain a contrast factor from 1.0.
Cine intermediate film have a good color reproduction.
For best quality I project the slide onto 4x5 panchromatic sheet film (TMX) and process that. You could also use a 'slide copy' attachment for your 35mm camera and copy the slide to negative film that way. that way.
It's easy to make a lousy interneg, and surprisingly difficult to make a good one. Nearly all commercial labs did it the lousy way, and that was what gave internegs an unfair bad rap. But yeah, I have a clue how to do it. Use those slide copier gadgets if a Holga camera is too precise and high tech for your taste. If you area serious, you'll need to spend some money and be willing to spend a lot of time practicing the chords before you can play a symphony. Since official interneg films are either extinct or some old by now as to be useless, your best option is going to be Portra 160 sheet film. Controlling the contrast of the original chrome is done via unsharp masking. And you need a good colorhead, preferably enlarging the original precisely onto stable Portra sheet film. If the original is Velvia, pray.
If I could talk about hit here, I'd say drum scan the neg and output to lightjet for a superior result. That's what I do but I don't talk about it![]()
B&W is what I do but the OP would use color neg sheet film.As we're in the "color" part of the forum, I was under the impression that the OP wants to make color prints from his slides?
Do not use a cine film. You will have a contrast mismatch.
You mean cine film would need contrast adjustments just like Portra, so we should just go for Portra anyway?
Just out of curiosity, I ask: what is the main characteristic of an internegative film?

Lower than average contrast, and
A curve that is optimized for creating negatives from transparencies.
Thanks, Matt!
I am still a little confused, trying to make sense of different films and their characteristics.
I've just read this and found that Kodak recommends preflashing internegative film for contrast reduction.
I still don't understand what PE meant by "contrast mismatch".

That link you refer to is to 2273/3273 , a motion picture product.
(snip)
Motion picture print film has radically different contrast when compared to colour photo paper.
Motion picture negative films are low contrast, and consumer / professional negative films are high contrast. Therefore, motion picture print films are high contrast to give the right contrast to the image. Color paper is lower contrast to give the same contrast range to the image.
Mixing the two systems will give a "contrast mismatch" with contrast generally being too low, and images appearing muddy.
A preflash is not needed. See my attached photo above (Ektachrome > Portra 160, pulled process then scanned). I have a scan of the print as well.
