I'm having an issue with a GY-HM100U which has otherwise been a great camera. It may be operator error, but I can't figure out what.
I'm shooting a whiteboard. I've gotten the exposure issues fairly well conquered - but now I've noticed another issue.
In shooting the whiteboard, when the artist puts his hand into the shot, the white board gets brighter! I'm shooting in manual mode, manual focus, manual exposure. It's the weirdest thing. I have - essentially a white screen with some black drawing on it. When the hand and arm goes in, something inside the camera tries to compensate for something - and the whiteboard gets brighter. Resetting the defaults and returning to manual focus and exposure doesn't help. What am I missing?
