Canon Powershot A560 Adobe Dng strange colors


#1

I’m trying to develop a picture i took with a Canon Powershot A560 (not mine), Raw Therapee 5.5 release.

With the original chdk’s dng i get right colors, with a dng converted with Adobe Dng Converter (in order to get a lossless compression) colors are completely off.

The original dng is on raw.pixls.us -> https://raw.pixls.us/getfile.php/2918/nice/Canon%20-%20Canon%20PowerShot%20A560%20-%2010bit%20CHDK%20ver.%201.4.1%20(4:3).DNG

The converted dng is attachedIMG_2641.DNG (4.6 MB)
(i have tried with ufraw-batch and it is converted ok).

Thank you in advance.

This is what I get opening IMG_2641.DNG in RT 5.5 unstable with White Balance set to Camera and using the Adobe Neutral profile for the Powershot G15. If I use the RT Camera Standard input profile I get the same thing as you.

I fear that it doesn’t solve the problem. If you have a look at the white balance sliders and move it, you see that something is not going ok.
Perhaps a bad interpretation of some matadata?

You are right. I didn’t pay attention to that. Lightroom and Darktable seem to be able to read and adjust the WB OK.
