Hi Rene,

Thanks for the feedback!

Making the setWhiteBalance call should be ticketed here:
https://code.ros.org/trac/ros-pkg

I think that you should be able to determine whether your camera has
automatic white balance by playing around with SampleViewer in the
prosilica_gige_sdk package. Are there attributes related to AWB, for
example?

Correct. This is normal until you calibrate the camera.

Since you are the only person who knows the specifics of this problem,
it would be really useful if you put a few lines about the symptoms
and how you solved the problem on the troubleshooting page:

http://www.ros.org/wiki/prosilica_camera/Troubleshooting

If you do not yet have an account, you can create yourself one.

Here I believe that your main problem will be getting the timestamps
from the two cameras to exactly match. I have heard that there is a
node to do this, but am not sure off-hand what it is called. It is on
a non-WG repo.
