Digital BW, The Print

I should add though that one of the bigger issues facing digital cameras is
their exposure/metering systems.  Designed for film these systems have not
made the transition to exposing for the linear nature of a chip.  They still
meter for a "middle grey" - not necessarily 18% but still a middle grey of
some sort.  The manufacturers still have a leg in either camp.  Their
metering is film centric while the capture plane is digital.  The sooner the
two are properly aligned the better.  In my humble opinion, a change here
will do more for 35mm digital quality than a few more pixels.
