Digital BW, The Print

Austin,

Are you sure this statement is correct? From everything I've read, a normal
digital camera has sensor cells that measure luminosity and one colour, and
are arranged in various arrays in the proportion of one red sensor, one blue
sensor, and two green sensors. Each sensor output gives rise to one pixel,
the missing color values for each pixel being interpolated from the
neighbouring sensors.

So if the camera has 4 M sensors, it will at the very least produce 4M
pixels (all of them interpolated of course, since none of them has all the
color values). It may produce more, depending on whether the
hardware/firmware/software produces interpolated pixels that are totally
derived from other sensors.

So,
