Hi I am new on here and would like to ask some advice on camera settings for flying my GH3 and GH4. Obviousley I cannot adjust the settings once the camera is airborne. We have been caught out a coulpe of time shooting in manual when there has been a sudden light change. Is auto really a no no. Below is an image of the day in question when we had to chase the Steam train along the viaduct.. you ever tried telling a steam train to reset? ;-)
