Hey Shade, to see, simply flash the camera with right click holding. It should be more than bright enough to see.
Don't worry, you have plenty of flashes, however turning the camera off and on will drain your battery quick, keep that in mind. And if for some reason you do run out of battery there are batteries littered around the map.
Turning up the overall gamma will unbalance the game, and negate the usefulness of the camera.
I really hope you give the game another go.
Thanks.
