Making Internegatives - Which is better?

[newcan1]

if making 35mm internegatives, does anyone have any experience using ECN-2 movie film? I would have thought the lower contrast might make it suitable.

ECN is NOT NOT NOT designed for making internegatives this way due to contrast issues. It will generally not make good prints.

I managed to peg even a highly contrasty Velvia image or two with a Portra interneg. ... But it was a chore! Basically, I made the interneg from
a master reduced-contrast dupe intended for Ciba printing rather than the original neg itself! That involved multiple masks in the first place.
Yet because it was all done 8x10 contact, each step, even the final 30x40 print came out rather crisp. But color balance was luck of the draw. Never accurate, but sometimes nonetheless attractive. And the tonality was excellent, which would certainly not be the case with a direct
interneg of any type; So unless I make some quantum leap myself, I wouldn't really recommend Velvia as the best candidate for internegs on Porta. E100G or old-school Ektachromes, maybe.

I should add that I also have a "Reverser", well two actually, that fit on my Nikons. These allow the use of 35mm film for making internegs a roll at a time. I use a white card outdoors and meter for the f32 aperture of the Reverser and then shoot away, one slide at a time.

They are just as good, but a tad grainier due to size.

I've wondered about that, if we could just get one of those camera gadgets designed back in the day for slide uping and shoot copies of our slides on negative film - if contrast builds one could even pre-flash a little. Is that what you're talking about?

 

[Photo Engineer]

Yep, I have two of them. They are handy and work just well enough to dupe slides but you have to choose the scene carefully if you are doing pos-pos duping! Pos-neg dupes are just fine.

Would such a device work well for making B&W slides by copying B&W negatives onto negative film? Contrast could be controlled to a large degree by appropriate exposure and development.

I also don't think there is any RA4 paper without back printing.

Arista RA4 paper has no back-printing. I can't say it'd make a good interneg compared to Portra, but I've considered putting some in my camera one day.

I used ECN film (250T) for internegatives and the prints were good enough for me.

Yes, you can make B&W slides from B&W negs by adjusting the contrast.

Color paper has such short latitude that the images would be high contrast and quite dupey looking. Same thing from cross processing RA4 in a reversal process. High contrast.

If you think the ECN prints look good, then go ahead and use it. However, the prints are not as good as they could be due to the contrast and latitude mismatch.

There, three in one.
