You could stabilise the camera with a gyroscope, spinning around a vertical axis. It would consume power to keep it spinning, and, by definition, it would add weight, but if the camera was pointing straight down when the gyroscope was started, then the gyroscope would tend to keep the axis vertical. And you wouldn't need to care where the balloon went, as long as it went somewhere you hadn't mapped yet. Or something.
