I have a few little niggles:\n\n* The night mode is still a bit vague. I don't have much of a feel for\n whether there is a reasonable default behaviour for this. I suppose\n we could just say that frames are labelled long/medium/short\n according to the implementation?\n\n* I've said vaguely that frames cycle between short/long or\n short/medium/long according to the implementation. Do we need to be\n signalling which category an implementation falls into?\n\n* There's no clear reason why HdrChannelNone exists. I do believe it\n is useful, not just for Pi users who might want to mess around and\n do unusual things, but also when switching exposures reliably from\n frame to frame proves difficult (because it is quite hard to do\n right).\n\nThanks!\n\nDavid\n\n\nDavid Plowman (1):\n libcamera: controls: Add controls for HDR\n\n src/libcamera/control_ids.yaml | 87 ++++++++++++++++++++++++++++++++++\n 1 file changed, 87 insertions(+)" }
