Hi,

Today the German news page Heise foto published[1] an article titled
'Colored infrared images from the RAW converter'. It deals about
converting the colors in those images from RGB to BGR, so to switch the
red and the blue channel. This gives the images a more natural look,
e.g. the sky is in infrared images red. The author Ralph Altmann wrote
that using the proprietary programs they tested it's quite hard and
complicated to do this, as opposed to the OpenSource software available.
He tested Darktable, Digikam, GTKRawGallery und RawTherapee, all of them
were able to do the switch but with different practicability and
difficulty. It was the easiest with darktable by using the 'input color
profile' module (de: Eingabefarbprofil).
To adjust the effect, it's possible to use the channel mixer (de:
Kanalmixer).

Along with their recent test on OpenSource raw converters and
darktable's, this seems to be turnaround by the heise publisher, as they
have put the free software word in second place by then.

Sebastian
