This is a draft of a change along the lines of the discussion in gphoto#968 (comment) meant to be able to discuss something like that further. After realizing that there is no event sent from the camera to reliably detect the moment the camera is ready again, I went back to the approach that I successfully used for the last 10 years in production. This allows me to execute the following command on my R8 to capture a total of 4 images in under 2s. gphoto2 --set-config capturetarget=1 --set-config aeb="+/- 3" --set-config-index drivemode=1 --set-config shutterspeed=1/500 --set-config ownername=400 --trigger-capture --set-config aeb=off --set-config-index drivemode=0 --set-config ownername=1 --trigger-capture The use of "ownername" is obviously not meant to stay, it was just a quick hack to enable me to pass an sleep_ms parameter into camera_trigger_capture from the command line.
