i just bought my first minidv camera, a canon zr900. when i pan across an open doorway to a room with brighter light than the room the camera is in, the exposure level (gain?) will adjust and the apparent brightness of the walls of this room will change, i'm guessing so the overall average brightness will be within some level the camera considers acceptable.
is there any way to prevent that adjustment from happening, maybe to lock the gain or whatever, sort of like you do with white balance? it does this both in "easy" mode and "program" mode.
i've read the user guide, but there are surprisingly few manual controls on this camera:
Consumer Camcorders - High Definition Camcorders - DVD Camcorders - Single Chip CCD Digital Camcorders - Digital Camcorder - ZR900 - Canon USA Consumer Products
what is the correct terminology to describe the automatic adjustment my camera is making here?
