Re: CMOS vs CCD digital

ER,

an interesting concept—I've been following the Foveon chip since it was
announced. I like the idea that the chip records all three colors (RGB) at each
sensor site—this should give much better sharpness in images and perhaps
sharper black and white too. Other technologies use a staggered array of sensors
for seperate recording of R, G, B. Then they interpolate the colors in between
—which is where you get some color shifts and loss of sharpness.

I'd like to see an image shot with it and compare to the D1X.

It should be noted that this is effectively a 3.4 megapixel camera, but with
greater sharpness than other 3.4 megapixel cameras. The 10.2 megatpixel
headline is derived by adding the red, green, blue layers at each sensor site.
To their credit they explain this.

If this technology works well and handles a wide subject brightness range,
long exposures, and gives accurate color, then there will be some great cameras
made with it.
