Is there a way to dynamically control webcam exposure settings in ROS?

I am currently working on a project that detects objects using a webcam. My algorithm is working well in good natural lighting conditions but when the lighting conditions change or if the light source isn't very good, the webcam seems to have difficulty setting proper exposure. I would like to be able to dynamically change the exposure so that if the image is too dark or too bright i could override the webcams exposure settings. Also I would like to look into doing something like HDR to better detect things in harsh lighting conditions. Is there a way to do that through ROS? I'm using a Logitech C90 webcam and OpenCV for my image processing.

I've looked for this as well, and none of the existing USB camera drivers appear to do it (The firewire driver does). Perhaps someone else is a aware of a better driver.
