A recommended RAW converter – RawTherapee

For this post  about noise removing (Reducing render times in Cycles – Noise filtering) I used the trial version of NeatImage.

Now I would like to recommend you a free app, called RawTherapee, which is primarly developed for photographers to enhance their photos, but could do the noise filtering for rendered images, too (of course).
As a photographer I have to say that it is quite OK, even compared to commercial apps.
