Re: USB MS Lifecam HD 3000 Exposure Issues

In the code I am setting the exposure by making it custom.
When I set the exposure to zero, the camera sees a green target and recognizes it properly. However, even when I change the value to one, the camera sees a white target and cannot find the target. I will change the values to go from one to one-hundred, and I cannot see any change. So, is the exposure acting binary, or am I doing something wrong?

We had this problem (although the exposure change was going from 5-6). Our solution? Tape a polarized sunglass lens over the camera. Works like a dream.
