Another thought. Why would converting the linear CCD output to non-linear A/D output have "not as much (good) information"? I could understand this if the CCD was outputting digital information and arbitrarily reassigning the values caused stairstepping type errors, but the CCD is analogue. What it's outputting is voltages. Can't the conversion be profiled?
