thanks! i think i got this working again. for now my stance at positive film is just that it simply skips the printing step and uses the “scan film” code path that i had previously. will do some cleanup/testing and push.

there is data from color positive print paper, like Kodak Ektachrome Radiance, that could be added to print positive film, I’ll have a look at it.

While travelling and trying out a couple of relatively new lenses including a 9mm f2.8 AstrHori lens I thought about this post. I feel some of the look of film stock was not just the film itself but the softer lenses that were around at the time. Now with digital we have very sharp lenses and editing options to sharpen the images even further. The classic USM mask used in digital editing is based on a concept designed in the days of sheet film. I wonder how many if any film photographers here ever made a unsharp mask for printing their film stock. I will be surprised if anyone says they made one to sharpen there film images.
Been reading this thread for some time and have been using the software for some professional. Game changing stuff! I actually shoot mostly on film and ra4 print, Andrea if you need any real world testing let me know! I have acess to endura but mostly print on DPii paper.

Support for some positive films was added recently to spektrafilm and ART.
Get latest spektrafilm repo and switch to the dev branch:
git clone --recursive https://github.com/andreavolpato/spektrafilm.git
cd spektrafilm
git switch devFollow installation steps at https://github.com/andreavolpato/spektrafilm/tree/dev
I used the conda method on my Fedora 43/Gnome OS.
Get latest changes in ART repo and update the command line in ART_agx_film.json for your system. E.g. I have:
"command" : "/home/andrew/.conda/envs/spektrafilm/bin/python3.13 spektrafilm_mklut.py --server",Here are a couple of examples:
Provia 100F:
Kodachrome 64:

I’m trying this with 1.26.3 on windows…I grabbed the new scripts but I haven’t built ART in a very long time so I was wondering if that might be my issue??..Spektrafilm is installed and runs the gui but either I can’t land on the right command syntax for the Python line in the JSON file or I need an updated build for ART but I can’t get the integration to work in ART.
A cool feature to add would be enlarger diffusion! When you put a diffusion over the enlarger lens you can get the shadows to bloom instead of highlights because everything is inverted, its a very interesting look and tons of folks i know who work in editorial and fashion use it. Will link an example by Jack Orton who uses this method.
