Has ANYONE been able to get images out of the life cam, using ANY method, that comes anywhere close to being as dark as the sample images for the FRC vision processing? I'm beginning to think that the LifeCam is simply not adjustable to that low of an exposure.

The Javadoc notes that exposure and brightness go from 0 - 100 are completely wrong. I forget what the actual range is but this issue frustrated a room of students and mentors for most of a Saturday until we played with the MS software for the LifeCam which actually presents sane values for the 3 different settings. Brightness is something like -15 to 4 (don't trust that number, I'm going from rough memory) but not 0-100 at all. None of them documented to be 0-100 actually are.
