[darktable-user] How to darken a particular tone?

[Colin Adams]

I want to darken the (reasonably monotone) background of a picture. I can
use the colour pick to get the RGB values. Which module(s) can I then use
to darken that tone?

You could use modules like exposure, brightness-contrast-saturation, zone
system or tone curve, and apply a parametric mask. The colour zones module
allows selection based on hue or lightness or saturation, and you can
combine that with masks, too.

I would try the "color zones" with the lightness tab.

[Colin Adams]

Thanks.

But I'm having difficulties with this. I'm trying to use the exposure
module to give a negative exposure compensation within the range selected
by the mask.
The first difficulty i'm have is that the RGB values given by the colour
picker in the left pane (54, 59, 55) differ greatly from the values shown
by the colour picker tool for the parameteric mask in the exposure module
(9.0, 9.7, 9.1). Why are these different? Should I just ignore the colour
pick from the left pane?

Thanks.
That's working well in conjunction with a drawn mask.

Re: [darktable-user] A better starting-point for Nikon RAW-files

[André Felipe Carvalho]

Hello,

I've following this thread with great interest, since I have a Nikon 7200
and I was even thinking about developing from jpegs instead of raws.

Could you please instruct me with what to do with those .icm files? e.g.,
where to put it in my system. I know it's for the D7100, but since Saint
Germain reccomended it, I would like to git it a try.

And about the generation of .icm files specifically for the D7200, if
someone could send them to me, I would greatly appreciate it.


Thank you in advance!
André Felipe

What's the command to open a .icm file in gnome-color-manager? I'd like to
look at one of my Nikon D810 files.

either you double-click in Nautilus or Nemo or type


bash$ gcm-import 
in a terminal and you should see the attached dialog, you click "view 
details" and can start investigating ...

I've tried your profiles with my D7200, and I can confirm

I can see a slight blue/green cast and the colors are less

I'll have to generate my own profiles to be sure (perhaps

Re: [darktable-user] A better starting-point for Nikon RAW-files

[Colin Adams]

OK, thanks.
I did that and then used gcm-view to see if there were any problems. All of
them except one were colorspace YCbCr and no problems were reported. One
was colorspace RGB and has the problem "The profile has the following
problems:
• A scum dot is present for media white".

So "unsupported input profile has been replaced by linear Rec709 RGB!" from
darktable is presumably because it is not supporting the YCbCr colorspace.
Would that be correct? And if so, is there a way to convert to another
colorspace?
