applying lut to image commandline

hello, people.
i am trying to use gmic from commandline in order to apply luts.
i have read the manual, and even found the handbook.
so, when i do lets say, for a test,

gmic -input test.jpg clut analogfx_soft_sepia_ii,48,0 -output test2.jpg

or just

gmic -input test.jpg clut analogfx_soft_sepia_ii -output test2.jpg

or choose any other lut, i get two output images - one is the copy of the input, and second is the lut image itself, i guess.

but how i can apply the lut to image?

Hi @inky and welcome!

Probably like:

$ gmic test.jpg map_clut analogfx_soft_sepia_ii -o test2.jpg

thank you very much. already found it out from the @Claes’s link.
converted a couple of images using all profiles by small script, to look, which luts I like more, and if they look similar to the luts I have.

btw, how the film luts were made?
with color checker, under reference light?

was that the dedicated project, or where all those lut come from?

and then, how do i use other, already existing luts in .csv or .cube formats? lets say i have downloaded fuji’s eterna lut profile, can I apply it commandline?

so my tests are
