Digital BW, The Print

Anthony,

Surely every pixel on a digital camera (except for a few exotica) is
interpolated? The skill of the camera maker is surely in choosing the best
size and number of sensors, their physical arrangement, and the
interpolation techniques.

For example, a Nikon D1x has a chip with 4028 x 1324 sensors, but the image
produced is 3008 x 1960 pixels - all interpolated !!

As to 6 mpixels being all one needs, I can see the difference between my
current scanned and printed images with 24 mpixels and my previous ones with
'only' 11 mpixels. With just 6 mpixels an A3+ print would only have 167 ppi
! With 24 mpixels I can send 330 ppi to the printer - in the recommended
range.

Bob Frost.
