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?
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
http://norayr.am/gmic_test/0/
http://norayr.am/gmic_test/1/
what about applying a custom .cube lut from commandline?
i actually did not find it in gui either, some old youtube videos reference user-defined settings, where it is possible to choose the cube file, but now it seems it is gone.
anyway, it is more interesting to find the commandline because i am applying the luts to all the photos in a directory via script, to not make it with each photo.
thank you.
@David_Tschumperle @Claes sorry to tag you, just i am not sure you got the notifications. and i am not even sure this is possible.
Something like:
$ gmic image.jpg clut.cube map_clut[0] [1] o[0] output.jpg
ok i’ll just leave it here, that it doesn’t exactly work, and i don’t understand from the manual what are these [0] and [1] and o[0], but thank you!
Those are the image indexes, the order of your inputs (unless you change it with another command). In the example, [0] represents image.jpg and [1] represents clut.cube. map_clut[0] [1] means you are applying [1] to [0] and o[0] means you are outputting [0]. o is the shortcut for output.
