A Mathematica function
DeviceRead["RaspiCam"]
returns an image with default camera settings.
A more powerful and versatile way is to reach out to the RPi's function raspistill:
image = Import[ "!raspistill -n -w 600 -h 400 -t 120 -o -", "JPG"];
This form gives you access to the cam's exposure options, descriptions of which can be found from the RPi in Terminal with
raspistill -?
The best source of support is, I think, the Raspberry Pi group on Wolfram Community.
