I have been able to get the camera working pretty well in two locations by adjusting the brightness.
At our playing field there are long fluorescent lights attached directly to the white ceiling. As you can imagine, this lighting is very bad, it causes whatever is in the foreground to bleed into the ceiling where a light is. However, I was able to get it working by setting the camera's brightness to 25. It was here that we shot our
promotional video.
At our shop, there isn't as much light, so a brightness of 30 works well. Towards the end of build season I would work all day in the shop and around 3:00 PM the sunlight would shine through a window and blind the camera. A piece of cardboard over the window was enough to get it working again, but once the sun was low enough, the light was to low and I would have to take the cardboard off to make the camera work again! In other words, variable light is bad for the camera.
Good luck to all teams with their camera calibration!
