Marc,
did you by any chance get to look at the Foveon digital camera?
Foveon apparently has a stand of their own there. It should interesting to
see the 2.5m high Foveon print at the stand. The approximately 2.4Meg linear
(fullRGB) pixel resolution claimed for their latest sensor thus corresponds
to about a 1mm pixel size for the 2.5m enlargement. Some of their press
releases imply the sensor can resolve higher resolution for fine detail. It
may be they have a higher pixel count and do some local processing on the
chips to reduce moire /aliasing noise before saving the data at a lower
resolution. This would fit into the previous work of Carver Mead (Foveon's
founder) into analogs of neuronal networks for retinal and audio signal
processing.
Hassellblad also has just announced they will use the Foveon
prism/sensor assembly with a new camera of their own. Did they show
prototypes by any chance? Interestingly the Hasselblad camera aparently
will accept some Cannon lenses with an adapter! This is probably just because
the Foveon system currently supports these lenses.
Let us know what the results look like if you get a chance to view
any prints.
