Hey, I'm still pretty new with my spark, but I'm having trouble with auto mode when taking stills around dawn and dusk. If even a little bit of the horizon is in the shot, the whole image wants to goes dark. I have to aim lower than I like to get it to focus enough on the land and scenery to brighten up. Is there any kind of spot metering mode that I can use to keep the camera on auto but use the center of the frame for light balance?
