Hi,
blue LED light sources. They put them now in all places giving us
photographers a severe headache. Horrible.
The manual tells you what to do:
http://www.darktable.org/usermanual/ch03s02s10.html.php (see "3.2.10.5.
Unbounded colors" and "3.2.10.6. Possible color artifacts"). In essence,
you need to activate the gammut clipping option in the input color
profile module to deal with those situations.

Hello,
I've started using darktable few months ago, and I'm very happy about it.
But there is still some problems that I cannot understand how to solve.
For example, in this image
https://dl.dropboxusercontent.com/u/2155571/artifacts.CR2
I see a lot of blue and purple artifacts in the lake. I thought they
were highlight spikes, but if I convert the image in black and white
they are rendered black.
I don't understand if this is a bug or just some default options which I
should understand how to tune.
The photo is a long exposure RAW taken with a Canon 6D (details in the
exif).
Thank you for any help :)
Lorenzo
