Re: [darktable-user] input color profile

[Jean-Luc CECCOLI]

Hello,

I could get an explanation to my problem, and I felt very confused.
When starting using my D4s, I did not create any profile for it, used a neutral 
basecurve instead.
Then updated to DT 2.6 *and* in the same time created the profile the (I 
thought) same way I did for the D700 some years ago (see 
https://www.youtube.com/watch?v=O1nS3URVSYA=youtu.be).
Well, in fact, it was not identical : ViewNX had become ViewNX-i, and the 
profile generated was not RGB but (how could I have known it ?) ycbcr, which dt 
does not handle.
At this point, 2 possibilities for me :
1- use the same profile as for the D700,
2- create a specific profile for the D4s, using one of the multiple tutorials 
on the subject (for instance : 
https://pixls.us/articles/profiling-a-camera-with-darktable-chart/).

Rgrds,

J.-Luc

You should be able to workaround the issue by shortening the name of the icc 
profile. If this does not work for you then you face a different issue and need 
to file a separate regression report.

Hi guys, I just confirmed the way to go is to file a regression on github. How 
it works: We need an icc file and the dt version that was working fine with it 
as a start. If we have that we can then find the commit that broke the icc 
support for nikon icc files. As it never has been working for me can you please 
give me the freshest dt version that still was was working together with your 
icc file? (please verify that it was working before). You can also file a

Re: [darktable-user] input color profile

[Jean-Luc CECCOLI]

Hello,

No, this does not work for me. And I doubt it works for Michiel as well, since 
he writes (1st post) that he has shortened the name of the profile with no 
effect.

I opened a new report : https://github.com/darktable-org/darktable/issues/2438

There seems to be many regressions for Nikon cameras since latest 2.4 version 
of dt.

Rgrds,

Exactly, those extracted Nikon camera profiles

I have been using those with my D300-images for some years now, but since the 
DT2.6 updates they are not recognized/used, alltough I see them in the input

I use the 'old- darktable'-snap which handles the profiles as it should...

Hi,

As of today (with darktable2.6.1) it seems Darktable is not able to read my 
Nikon-camera-profiles.

I notice that they all give the same output as the 'linear Rec709 RGB'-profile.

To check if it is a folder-problem I have placed a random profile in the same 
folder, but that one works fine.

Then I changed the (really very) long profile-name to something short, but that 
had no effect.

What can be a solution?



Thanks,

Re: [darktable-user] Input color profile for Olympus OMD-EM5 Mk II

[Jean-Luc Lacroix]

Just put the icc files in $HOME/.config/darktable/color/in/ directory 
(create it if not exists).


Restart dt and they should appear ine the "input color profile" module.

Cheers.

There's also a base curve based on the default E-PL6 output, as a
dtstyle. You may want to try that, too, in combination with either
my color profiles or the standard ones.

Using these profiles with any substantial base curve gives rather
strong saturation, so I also usually auto-apply the color
correction module with saturation set to something like 0.85, for
something pretty close to out-of-camera rendering.

I used the method outlined here to create the profiles:

The following links give some insight into how a lighting-independent (within 
reason) color profile is prepared:

[darktable-user] Input color profile

[ternaryd]

Hi,

I was just wondering how an input profile for a
camera works in darktable.

If I understood right, an ICC profile also
includes the white point, but the lighting
conditions can yield a different white point,
and darktable allows me to change that. Does
this mean, I would need a different profile for
each lighting condition?

Aren't the base curves as distributed with
darktable basically like a profile? What white
point do they assume? If they yield a maximum
intensity per color channel, some white point
is implied, right?

Thanks,

Re: [darktable-user] Input color profile

[johannes hanika]

note that our input colour profile module has a `BGR linear infrared'
profile for this purpose (so you can work on your swapped channels
early on in the pipe, channel mixer comes in quite late).

[darktable-user] Input color profile

[Raymundo Vega]

Hello all,

I am playing with infra red photography and need pointers on how to
create icc files, i like to try different channel mixtures.

Any help is appreciated.
