Let me rephrase that, in all of Sigma's printed Ads on the SD9 and SD10,
they look freakish (the giant eyeball), plasticky skin (the latest model
with no skin pores with weird colorcast), and plain ugly. Photographers
have nothing to do with it :-)
I have nothing against Sigma or Foveon per se. I don't own a DSLR and 99%
of my shots are on Provia. The proofs are on the pictures...

Ha ha. One of our customers for the Atmel AVR compiler was a little outfit
called Silicon Film....
As I said earlier, the bottleneck for DSLR is IO bandwidth. Custom HW buys
you faster IO throughput generally, not faster processing (generally). You
can have 20 gazillion megapixels but if you have to wait for it to write,
the game is over!!!
This is probably why I will stay with film cameras for a while yet. I have
now gotten Color Management under control. My scanned pics look very very
close to what's on the slides. So all I have to do is to make sure I have
good pictures on the slides to begin with!
