So Im experimenting with just shooting photos with ortho lith film, but i wanted to show how they looked displayed over black ink, black water color and painted with black watercolor. I think id like to display them with a mat, glass and frame. It seems very seldom discussed on the internet and Id love to hear your opinions and experiences.
Very interesting, what type of film and developer combination are you using? I've read and seen that Litho film is a very high contrast type film, but these look to have a better tonal range then expected. It seems like more folks go with X-Ray film in lieu of Litho film.
Unfortunately I don't have much experience with this process but would love to hear what others think, your progress and set-up working with Litho film.
Edit:
The look of how you're doing this is pretty cool. The ability to display in front of paper that has been painted looks like it can really expand the possibilities with this film.

When I still used xray film, I ran into the possibilities for doing this often. It helps if a film has little to no top coat so that the silver layer is effectively right on top of the film. This creates the strongest effect. Xray film meets this criterion.
To get good results, in my experience you want to expose sufficiently, but develop only briefly. Downrate the film by one or two stops (so overexpose +1 or +2) and reduce development drastically compared to what you'd need for normal printing. You want a very thin negative, but with good shadow detail. If you develop too much, highlights will block up as shown in the example you posted.
I played around with the idea, which I called faux-ambrotype. Litho or reproduction films work well, I used primarily (very) expired and somewhat fogged ORWO films (FU/FP/FN types). I found that phenidone or phenidone-rich developers work well, think POTA or XR-1, which also give you a higher EI. I developed the sheets in a tray at 30C for what I recall were extensive periods of time, which yielded positives that could be viewed without a black backing due to the high buildup of density. In fact, I could only scan the images in reflective mode on a flatbed and I never attempted optical printing. I did find it works better for low-key photos due to the loss of separation in the highlights.
I'll look around for examples.
Yeah, I would increase exposure significantly and reduce development as well.I think I need to expose the film more right?

The nice thing with Ortho film is that you can develop by inspection; I would recommend doing so. Stop developing as soon as the important shadows are just visible. If the highlights don't show sufficient differentiation anymore by then (i.e. they're blocked up), you know you need to further increase exposure on the next shot.
It's essentially the same approach as making ambrotypes (you know, with collodion). The main difference is that your material is much faster to expose and much slower to develop. And the film approach is a lot less messy of course.
Some x-ray films are single sided - primarily ones for mammography I believe.I would love to try x ray film, but after reading its double sided, I dont know how to adequately protect the back side from scratches.

I don't think I've seen any X-ray stock in sizes smaller than about 6x9 inches (or metric equivalent) other than dental (which is closer to 3x4 cm) -- but I haven't looked that hard. The main reason folks use X-ray is that it comes precut to 8x10 film holder size, but costs about what economy 4x5 camera film costs. You'd need a darkroom to recut it, though.
Does Ilford sell their Ortho 80 in 4x5?
I don't know. You'd be catering to a crowd that is very cost-conscious (not to say they're cheapskates for a large part), many of them will buy once and never return (concluding xray or even sheet film altogether is not for them). It's not difficult, but I doubt it's fun. There is a market for it, however.That would be a pretty lucrative side gig, cutting down x ray film to 4x5 and reselling it.

And let's not forget that these "cost conscious" users are also going to be the first ones to complain about scratches, fingerprints, incorrectly positioned orientation notches, etc. Plus, to make this cost-effective and minimize safelight fogging (because the end user will also handle the film under safelight, adding to the total exposure before development) you'd want a machine that does the actual cutting -- pull a sheet from the box, drop it on the machine stage, pull the handle, collect the four sheets, notch them while maintaining orientation (mainly important for single-sided films, of course), then into the black bag for the new size.
I doubt you could sell the end product much below Arista .EDU Ultra 100 and still make anything close to wages, which would make it a labor of love -- which is a bad idea in this market.
You could also try developing the Ortho Lith in a print developer like Dektol 1+3 (or even higher dilutions, like the 1+9 usually used for film in Dektol) -- you'll get lower contrast, which you want/need, without having to shorten development so far you have trouble with consistency and evenness. Some say it won't work well, but we processed Kodalith in Dektol when I was in high school (though we did it at print strength, in print trays, under safelight, so we could snatch it at the right stage -- which is a recipe for inconsistent development).
Cyanotype can be toned to a near-black -- either directly (soak in strong tea) or by bleaching and then toning (also in strong tea). Either method converts some (the latter most) of the Prussian blue that forms the image into iron tannate, the primary ingredient of registrar's ink (and in permanent enough to last centuries under poor conditions). The tea toning will also stain the paper, of course, so you'll wind up with a blue-black or black on brown image, but it's a nice variation on the traditional cyanotype and won't fade if kept in the dark for many years as cyanotype can.
