I've gh1 (unhacked) and photos are not sharpness and it includes noises. In videos there is shadows and dark points has bad gradient also having banding problem. If i upgrade version 1.2 to 1.32, can it be fixed? And if i upgrade to 1.32 is it possible to hack it after ? And is ptool have a positive effect on photo ?
You posted question without citing camera model, without using tags and in wrong category :-) I fixed this for you, but for last time.
As for the question. I suggest you to learn photography and filmmaking instead of looking at cameras flaws and trying to overcome them by firmware or buying new camera.
