Re: Ring light not bright enough in camera feed

Next, you should change the white balance from auto to one of the ones built in. Play with the indoor and outdoor ones to see which results in the most saturated red color.

I typically do this in vision assistant. Feel free to post photos and it may be easier to diagnose.

My understanding was that exposure is set in the begin.vi, I don't know how you can just switch the settings while the camera is running. Also, you mentioned changing the white balance from auto to something like indoor. Again, when I look in the begin.vi, those settings (indoor, auto, ect) are plugged into the exposure.vi, I do not see anything about white balance.

Is there a simple way to set this up? Is that what vision assistant does, give me settings to use in the program for the camera?
