Dear Agriggio,

First of all, thank you for creating the make_arq code repository. I have a question to ask you. I have a Sony A7RIV camera that can shoot Pixel Shift images. For one scene, I can get 4 ARW files and one ARQ file. I found that the ARW files are 6376×9568 in size, while the ARQ file is 6376×9568×4. I believe that the ARQ file contains one R channel, one B channel, and two G channels. How can I get a demosaiced image with three channels?

Best regards,

Hi @happycaoyue, sorry for the late reply. You need to either use a raw processor that supports the pseudo-ARQ files produced by make_arq (currently only RawTherapee or ART), or use the -d flag to get an already-demosaiced dng file.
