It was dark enough that I don't anticipate GRIP having a problem with it - based on configuring the settings similarly with the USB camera is plugged in to the laptop.
Using the microsoft software linked to in the other thread, it was very obvious that the camera can be set up to change a lot more than we have access to with the class. I could turn the autofocus off, mess with the white balance, and all sorts of things that were useful in making the retroreflective tape pop even more. Unfortunately, I think we'll be limited to creating a good vision processing filter with just the brightness modified, though I'm going to keep messing with the exposure. But I am seeing the same thing you are - changing the exposure doesn't seem to have any affect, in fact at one point that camera stopped updating and I had no idea until I waved my hand in front of it to test something else.
Good to know it's just a wrapper...might be more investigating to do with the IMAQ functions.
