Hi
Ok, but I'm talking about the original resolution here, not some upsized version.
That's the problem I have with the DP1 ... from what I understand, the images are beautiful but at 2640 x 1760 its only marginally bigger than my ancient (in digital world terms) Coolpix 5000 (which is 2560 x 1920). That produces very nice to look at on print images up to about A4 while examination on the screen leaves a little to be desired at 100%.
At that point on the curve 2700dpi scans of 35mm negative produced nicer files than the Coolpix did even from RAW
from this overview
100% view of 35mm
100% view of Coolpix
more recent testing I did have Canon 10D (at 3072 x 2048 pixels) exceeding what I can get from any scans of 35mm film.
All this leaves the DP1 (in my opinion) a little out in the cold with its slightly larger than 4/3rds *(20.7 x 13.8 mm sensor
VS 18 x 13.5mm) yeilding significantly lower sized files than (say) a G1 or E-P1.
So if your target print size is A4 then I would say that the Foveon Sensor
kicks butt and gives beautiful images ... but if you go larger (or crop at all) then the more modern cameras yield advantages not found in the DP-1 strategy (which is pixel limited).
Before one gets too critical of bayer array, consider that 4 colour press images are also made up of an array of offset dyes not so dissimilar and relies on the processing system of the human vision to seem as a colour image. Some are quite good, so the methods can't be dismissed as fully flawed.
