The latter portion of the white paper discusses setting up the camera so that you are processing good images. Experiment with the WB and exposure and brightness to find a setting that is consistent between your shop and outdoors.

According to wikipedia, an overcast day is 1000 lux, and I believe the lighting for the FIRST field is about somewhere between 85 and 95 foot candles. These are comparable levels of light.

It is also typical for the FIRST field having the lights aiming into the field from each long edge. They do not shine directly into the eyes of the drivers at the joysticks. So the illumination drops off rapidly there.

If you have questions about what a camera setting does, you can look into the WPILib documentation, the Axis documentation, or perhaps ask here.
