IMAQ-USB- brightness change

[ABM26]

I'm using IMAQ -USB and associated VIs to grab images from webcam. I need to modify its brightness programatically. I was thinking about using property nodes to modify the brightness. However, I see that option is not available. Any inputs how to modify the brightness while I'm grrabing images and displaying it on VI?

Thanks.

What is the camera that you are using? Will using a BCG look up after acquire put in a while loop solve the issue?

As I mentioned in follow up post that  BCG look up after acquire put doesn't help. Hence I added new post with the attached VI. Thanks
