[Darktable spektrafilm presets] Calling all the creative minds

I am looking for presets to include in the darktable spektrafilm module. So I would appreciate if you could come up with something nice. My mind is thinking about @s7habo or @bazdesh but of course everyone is invited :slight_smile:

For all who can’t compile on their own, find builds here:

Edit: This module is a tonemapper. So disable AgX, Sigmoid, Filmic before you start. I think best would be a neutral pipeline and just spektrafilm so new users get ideas where to start and which knobs to turn for a look.

Module presets = no extra tone equalizer trickery and no way to force the users to use a specific WB right, haha. i will try to translate some of the python presets, will use this version of darktable.

Should the input be exposed for the midtones with neutral white balance?

This module is a tonemapper. So disable AgX, Sigmoid, Filmic before you start. Should have mentioned that. I think best would be a neutral pipeline and just spektrafilm so new users get ideas where to start and which knobs to turn for a look.

How many presets are we talking about? :smiley:

I think 5-10 in total would be good, so if you could maybe do two or three very different ones I’d appreciate that. But of course we could go full diffuse and sharpen and have many more nested presets

Well, overshot a bit. Heres 7, work on most images, very varied, though mostly “unauthentic”, not sure if I could approach these more scientifically. I could probably whip out lots more “lookers” though :smiley:

Let me know if these work - I never used the export/import preset thing so, just to be sure…

Thanks for these presets! KinoGolden is definitely my favorite. By the way, how do you come up with these names? I’m totally blank when it comes to this.

Yeah I also like what that one does to the photos.
My stupid inside jokes mostly, my general unseriousness makes it easy. The Skodachrome because I am Czech and we have our Škodas (simply clever), Velveetia I think speaks for itself; the two BW presets are a classic joke - started with the low contrast one, low contrast is like low calorie in a way, so low-cal, the other one has to be crispy. I thought there should be a preset based on the cinema stocks, so here is the cinema-kino meme, the golden one because it is based on Gold200 and because it kinda has that “golden” ages warm look. And the pastel one is just pastel. :smiley:

Thanks for sharing! Skodachrome is awesome :smiley: .

Just a thought: Spektrafilm is a module with a LOT of sliders. How about we feed the docs with some words from the respective presets creators on how they crafted their presets? That might further help understand what can be done with a module as opposed to enabling a preset, being wowed by it but not understanding how the particuliar combination of sliders works?

Good idea! PRs can go here GitHub - piratenpanda/dtdocs: darktable user manual · GitHub

Wouldn’t that fit better as a blog post? Could still be linked from the docs.

I dont think that my “fiddle with the sliders until the image looks nice” is good enough for a blog, let alone a manual… :smiley:

I was thinking maybe a series of presets such as:
density → low
density → high
With low being +2EV film +1EV print, high being -2EV film -1EV print. Or something along these lines? I think these are reasonable creative starting points.

My two cents… BTW, awsome work!!

I like that your presets are creative, artistic and they establish a certain mood to the photo. They are not necessarily technical or accurate to the film stock or this is how this film “should look like”. Your presets are more to the let’s having fun side :slight_smile: I am playing with Kino250D and KinoGolden and I like them a lot, I don’t know if I would have came up with these edits myself.

I am not sure I 100% know what you mean, but if it is what I think it is - the module presets in Darktable arent modular (hehe) as far as I know, they always override and include all of the spektrafilm module settings, so you would have to do these for all films etc…

Anyway, @piratenpanda, I had a thought about the default settings, do you think the module should 100% stick to the reference? I would personally vote for a different default couplers diffusion size/tail values, the default 20/200 make the images way too oversharpened imo, using 5/20 still gives you the color benefits without making the image look like its been through an oven :smile:

I’m open to discuss the default settings :slight_smile:

I’d vote for Kodak Gold 200 als default as I personally find Portra 400 a bit anemic - but thats of course primarily a matter of personal taste.
