I understand getting 3 spikes, but pure black and pure white may be
difficult to define. Maybe different shades of gray, which would show
multiple spikes in the histogram. I've never been very successful with
metering gray cards. Mine always seems to vary depending on the angle
of the light. Perhaps flat lighting is necessary for it to work
properly? Pure black may be hard to come by.
There is also a RAW mode with the C-5050, which I believe gives a bit
more range than normal jpeg mode.
I would be interested in any ideas for metering experiments with the
C-5050.
