If you look closely, you'll see that it's not pixelization : you do see large squares, but there are details inside these squares (as opposed to a large pixel which obviously doesn't). This looks very much like an interference pattern due to resizing (e.g. subsampling with an "almost integer" factor which results in sampling always the R pixels of your sensor for a while, then only the B pixels, ...). It's probably not a coincidence that the pattern you see on the image is the same as the color pattern on your camera's color filter array. Unfortunately, I don't know the algorithms enough to give a real diagnosis, and even less a solution :-(. If you're looking for a combination of modules, I'd look at the crop module (the crop factor may be the one giving you the "almost integer" factor), and the demosaic module. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ ____________________________________________________________________________ darktable user mailing list to unsubscribe send a mail to [email protected]
