I've modded the camera driver myself. nothing amazing at 100% compression free.
Just your file size will be bloated to 850+ KB and you'll still see watercolor effects.
Good thing is minimal jagged edges.

I've also set it to higher exposure time, going as far as 16secs exposure during low
light conditions. Terrible noise no matter what. Lowered the ISO speed as well, since
bombarded with noise.

I'll release the camdriver soon over here once I finalize it.
