[ros-users] webcam: stop automatic whites

[Trevor Jay]

I've had good luck with using guvcview to set-up the camera the way I
want and *then* running my ROS camera driver. Your mileage will vary
depending on which ROS webcam interface you use though. This only
works if your webcam node doesn't mess with the settings itself (I
know gscam doesn't, and I suspect most of the v4l-based ones don't
either).
