Subject: [Motion-user] PiNoir camera: bright at 800x600, dark at
higher res?
Message-ID: <[email protected]>
Content-Type: text/plain; charset=UTF-8; format=flowed
I just re-built my Motion Rpi using a RpI 3 with a PiNoir V2
camera (using v4l2, as installed from apt-get)
I find that at 800x600 resolution, the camera yield bright picgtures,
but if I try higher resolutions (1024x768, 1600x1200) it gets very dark
I also find that auto-brightness has no effect afaics.
Does anyone have any tips on how to get a higher-resolution
but bright picture?
thx
