Dear Devs/Users,
Does anyone know of a good introductory book on color space theory from a
mathematical perspective? I'm looking for an introductory text to learn more
about color. I have a PhD in pure math so any amount of math is good.

This release sounds really amazing! It's incredible what the devs have done
with darktable since the early 2.x days when I started using it. The quick
access panel sounds really cool as well as all the new colour modules. I can't
wait to try it!!

Dear Darktable List,
I am having a curious problem with false colour in darktable.
It happens when I use the D500 camera with fine detail. It does not have
an AA filter so I would expect some false colour sometimes. Here is the

Thank you SO much to all the contributors for this beautiful software.
It is one of the best programs not just amongst open source software but
amongst all software.
I've tried most of the Raw editing programs out there for Linux, and I
can safely say I would still have to use Windows or Mac for R
Good job. I recommend it every time a request for suggestions for Raw
developers comes up on DPreview. Not a big deal, but every little bit helps.

Another possibility is shooting Raw+JPEG. With this option you can still
tune the JPEG engine in the camera somewhat with most models, and if you
need to edit you can go to the Raw file. Also, you can make some minor
edits directly on a JPEG file. Also, for people who are already working
in JPEG, w
I'm going to agree with this one. It makes a lot of sense to first
desaturation with monochrome and then do split-toning. It's much easier
to feel out what the end result will be in this order.

It might also be useful to note this page:

Wow, this sounds outrageously cool! I've been using darktable since the
1.x versions and it has progressed so far. Thanks to all the developers
who have worked on it...it's my favourite open source project of all time!

Going to have to disagree with that, and I think at least some of it is
what you used first. I actually tried darktable before Lightroom and
just by clicking around I found darktable pretty intuitive. Trying to do
the same in Lightroom was confusing after that.

For some people that might be true, but the current system also has an
advantage: if the shot is already pretty good but just needs a slight
cropping, then only a little dragging in one corner may be required,
without much dragging. Then the click-in-square method for moving the
crop is actually us

Make a new preset where the base curve has no nodes (i.e. is a line).
When you are making the preset check 'auto apply this preset to matching
images'. Then click OK. It will still be on from now on but do nothi
Thanks for the explanation about the base curve, Aurelien. Makes sense.
The base curve seemed to be too extreme in some cases and caused
unnatural colour gradients to appear in skin tones. I have since
reprocessed about 100 shots with the base curve disabled and the
improvement is quite noticeable
Dear Aurelien,
It's clear that you put a lot of thought into this and I am eager to try
it. It is very helpful to see the GUI screenshots, and based on those I

Dear List,
This is mainly for the devs: I was just wondering if all cameras shot in
DNG format, would that make adding support for cameras much easier? In
other words, does it take a lot of time to add new support for each
camera's Raw format?

Yes they are needed, but I wouldn't want them cluttering up the 'basic'

I've been thinking a little more about this idea, and while some modules
might be better moved to other tabs (or a new set of tabs) like perhaps
'color reconstruction', the current setup still seems to make more sense
in some ways too. For example:

Hi!
I can certainly see the logic of your idea. I definitely prefer the
current setup, if only because that's what I started with. I think the
only way to see if this is a good idea is to poll users because I am
sure there are some that would like your way and some that prefer the
current way.

What about using just a regular circle with a soft edge, and optionally
using mask blur? That gets pretty close to what you are after. You can
invert such as mask as well.
