Thanks for spotting this. I'll fix that and submit the change to upstream libcamera. Obviously this will take a little while to filter through, but in the meantime you could use the mode named "custom" as a workaround. You'd have to add this to the tuning file, though I note that the imx708 tuning does not have the "shadows" mode either, so you'd have to add it there too.
Thank you, let me just say that i really apreciate the work that you all do, I guess I'll have to change the tuning file for the imx708 anyways (the color shading correction in the standard tuning is, as the kids say, very spicy). I guess i will have to work at that first.
Hi, your request is for a "shadow" AE/AGC mode? Can you also say what camera you're using. As I explained above, you can certainly define such a mode for yourself in the tuning file - please ask if you need help.
I'd certainly like to add something like this, though for the moment such changes are rather stuck behind all the Pi 5 work in the queue! But please bear with us... thanks.
Hi - thanks so much for the response. I'm using Raspberry Pi Camera Module 3. Yeah, I was interested in trying out a "shadow" AE mode. I was a bit confused about the tuning file/how to set that up - is there any good documentation on that?
There is some documentation in the tuning guide. Unfortunately that is getting a bit out of date now and is due for a fairly big update as soon as I can manage it. But it's still broadly correct.
