jdw153 Posted May 3, 2021 Share Posted May 3, 2021 Hi, This is in reference to Affinity's astrophotography stacking processing as described here: https://affinity.help/photo/English.lproj/index.html?page=pages/Astrophotography/astro_about.html?title=About astrophotography stacking Raspberry Pi's new HQ 12 Mp camera (using Sony IMX477 sensor) has ability to keep shutter open for over 3 minutes which opens door for astrophotography shooting without need for the more expensive DSLR commonly used today. I have such a configuration setup for testing. This link explains how the RAW is appended to a jpeg: https://www.strollswithmydog.com/open-raspberry-pi-high-quality-camera-raw/ The only software I know of today is a modification to DCRAW which can open and convert the RAW part to TIFF format: https://github.com/6by9/dcraw Problem is that the Affinity stacking process is needing original RAWs for Dark and Bias frames for noise reduction processing. With Affinity if I just open a photo taken by this camera the jpeg is displayed but apparently cannot extract and utilize the RAW. So my suggestion here is to add support for utilizing this camera's RAW format. Quote Link to comment Share on other sites More sharing options...
jdw153 Posted May 3, 2021 Author Share Posted May 3, 2021 A more recent (very technical discussion) associated with incorporation into LibRaw of this camera's RAW format is here: https://github.com/6by9/dcraw/issues/4 Quote Link to comment Share on other sites More sharing options...
