I wasn't sure where to put this. It's not at all Mars-specific but it is 'tech general'. I was wondering if a camera could be designed to respond to light levels in a way more similar to the human eye. Why are all our current cameras linear and therefore highly intolerant of wide brightness differences? Is this not a most unfortunate handicap in space where the surface brightnesses of objects are so hugely variable?

Could there be a useful way forward here? Has this come up before? If so could somebody bring me up to speed?
