Hi everyone,
I have a handful of Kodak Ektagraphic HC 35mm rolls. I don't really know where and why I got them. They've been among my photo stuff for at least 10 years and I want to either get rid of them or use them for something meaningful. That film is intended for slide copies of line graphics, i.e. white-on-black reproductions of black-on-white originals (titles for slide shows etc.).
If I read Kodak's data sheet correctly, its output density goes from 0.1 to 4.0 within a mere 0.9 range of input density, when developed in (there was a url link here which no longer exists) It seems about as steep as grade 4 or 5 paper.
Now I'm certainly not going to make slide show titles with it. I'm wondering if it can be used to create slides from regular pictorial negatives, which is something I've been wanting to try for some time now. Considering its response curve, it looks like this might work at least for lower-than-usual contrast negs. What would be appropriate means of reducing gamma a bit? Say, to record a neg that would fit on grade 2 or 3 paper? Can we predict how the film will respond to a dedicated low-contrast developer (POTA, TD-3...)?
