Camera Exposure Value

[ph423r]

I've looked through the manual, and searched the forums. but wasn't able to find anything on this. Does anyone know how to enable the exposure option in the camera (The 3rd button down on the left side)? For me at least it is grayed out, and I've tried messing w/ the settings, but can't seem to enable it.

That's used by the video camera.
