Now, imagine if you instead could simply select the source colors in a
picture (which you can!) and choose which target palette they map to (which
I think you cannot). This would be almost as quick as the normal white
balance tool.
yes, i agree setting the precise colour target instead of the offset
would be a nice addition to this tool. if i find time i might try a
stab at it. i'd be curious to see whether this does something useful
with a 24-checker thing.
I think the ideal workflow would be like this (similar to the commercial
colorchecker solutions): I would place my IT8 target in the first shot
of a series, and then later in darktable I would mark the edges of the
target in the image, and the positioning of the patches would be
autodetected (with some perspective correction). Also, I could select
the manufaturer measurements delivered with the IT8-target, probably
after importing the measurements as some kind of preset stored in
darktable. And then darktable would create a color style that I can
apply to the other shots in the series with similar lighting.
that sounds exactly like what darktable-chart is doing.
Not at all. This involves many, many steps. Heck, darktable-chart is
even a completely separate program, and requires you to export and
import different files, with some conversion runs inbetween and
importing results into darktable and all the other things I outlined in
my first message.
Then, in a
second step, I could decide to tweak the colors in some direction, e.g.
film-like.
you can do that in the clut module in dt now.
Yes, the 2nd step is there. But that's a very, very minor, and optional,
step. The main point is the 1st step, which is insanely cumbersome now.
Nobody would do that to set their whitebalance.
