The colors from the stream and images are weird. For some reason, the skin color is blue. This happens both with the NoIR V2 as well as the normal V2. Perhaps it's a white balance issue?

Thanks

The V2 camera is much more sensitive than V1. You can tune the parameters in the uv4l conf file. I forget the name if it
