Lowering resolution does not help image quality (only speed, the current 'default' seems to be a dumb n-th pixel readout) - unless I do it in software, with some sort of median/denoising filter. Or maybe figure out how to make a darkframe without bothering the user... (if you cover the camera with your finger you'll see there are plenty of hot pixels). At this point, though, I'd rather wait for final firmware and implement improvements based on that.
