I'm getting some non-linear reading for a few cameras. The 533 and 2600 are good, the others, not so much. Anyone know an explanation for these skewed numbers?

Re: Sensor Analysis gone wrong?
Hi,
I think you are referring to relatively low values for the 'sensor linear to' figures. These values can only be trusted if you have been *incredibly* careful to keep the sensor illumination level constant during the phase where the linearity is measured. It's highly likely that the low readings are just being caused by the illumination brightness changing at some point during that part of the measurement - just moving about in the room where the measurement is being done can cause this as your movements change how the light is shadowed/reflected around the room.
cheers,
Robin
