Re: Film and digital more similar than you think

All that is needed for digital cameras to record highlights like film is for the sensor gain to be regulated by an algorithm that mimics the rate of the chemical reaction of silver halide. Fully active at the low exposure levels and becoming fractional as the recorded light increases. That shouldn't be too hard. In fact it sounds like a firmware update at worst.

It's not that simple. If it was it would have been done long ago. The problem here is that you propose a software solution (adjust sensor gain) to a hardware problem.

But still, John Sheehy gives a better explanation, in hardware terms here http://forums.dpreview.com/forums/post/50784208
