The color calibration module includes several presets for B&W (Fuji, Ilford…)
Independently the t3mujinpack also includes several presets for B&W (Agfa, Kodak…).
The t3mujinpack B&W presets are available as a style.
I’d like to have have those presets in the color calibration module presets. i.e., when I choose the tab for presets in the color calibration module I’d like to see what’s there currently and those B&W presets from the t3mujinpack B&W set.
The t3 styles for B&W film emulation involves at least two modules: channel mix, tone curve.
I therefore can’t have them show up under the color calibration presets.
[I shall close this thread as the issue is resolved.] [Turns out there’s no way to ‘close’ a thread…]
Steven, Todd: first, I appreciate your response and clarification on what I should do.
So, I did as you suggested. I right clicked on the links, chose “Save Link As”, and thus downloaded about 7 LUTs into a folder. The LUTS are all Microsoft Edge HTML docs. In dt, I set the LUT 3D root folder in preferences to the folder containing the downloaded LUTS. With an abundance of caution I restarted darktable., brought up an image, went into darkroom, brought up the LUT 3D module. So far so good…
In the LUT 3D module:
a) I expected to find the LUTS in the right most tab (with three horizontal lines). They were not there.
b) I hover on the “folder” icon within the module. It says “Select a png, cube…”. I click on it. Up pops a “Select LUT file” dialog box for the folder containing the downloaded LUTS (which I had set in preferences). I don’t see those downloaded LUTS and thus can’t select one. I choose “All files” in the dialog box and thereby see the files I downloaded.
c) Selecting one of them has no impact on the image.
My guess: the files I downloaded are not LUTS. Opening one of them in Windows brings up the Edge browser with the (static) image of the GitHub page with the name of the LUT.
If you click on each file (I open in a new tab), do you see a preview? If so, there should be a “Download” button above the preview that opens the image in the browser, and I can then save that image via the right-click menu. That works for me, other options give me an invalid PNG file. (I’m using Firefox 110, that might be relevant.)
Yes, I tried that option too: click on each png file, see a preview, click on Download.
Clicking on Download however shows me the contents of my Download folder (which included the previously downloaded zip files) but doesn’t download (what I expected and you say works for you): the individual png file.
My browser is Chrome.
Maybe I should try the same in Firefox…(though, technically, it shouldn’t make a difference).
Its the naming I think… the | character is used to create categories as you can with styles etc… if you rename those out of the file names you can work with them… So I cloned the project and renamed them… this will kill the categories but here they are… t3mujinpack Haldcluts.zip (56.8 MB)
Todd, you got it right, I downloaded your zip file, unpacked, copied over the png files, and can confirm–with delight–the LUT 3D module is able to pick up the pngs.
Thank you, I appreciate your help very much.
I’m also relieved that I’ve reached a stage where a problem I ran into was not of my own making! No guarantees I can remain in that zone…for sooner or later I will come up with ‘operator errors’ that are all of my own making…until, then, thank you and Steven and others who responded to this post!
I hope you find them of some use. It would be interesting to see how they compare to the associated style. There are a few sources of fuji luts and DT styles out there again I am not sure which ones are useful as I don’t make much use of them. I did at one point find a lut posted here by a member for Astia … it was actually quite nice in some cases…
Much easier to integrate a LUT into a Style I created: all I had to do was add the LUT 3D module to the Style, activate it if necessary, point it to the LUT folder, and test the various LUTS (as if they are presets in a module) and see how they impact the image…
Integrating a Style into my Style…ends up complicating things and putting me outside my small zone of competency…
Question: for every image, upon activation of the LUT 3D module I have select a file (in my folder of pngs) and then flip through the other pngs. Is there a way I can set the LUT 3D module so it automatically selects the folder of pngs (which I have also set in my Preferences)? that way upon activation of the module I’d have the list of pngs (much as I have presets in color calibration, color balance rgb, etc.)
