Tom - it's worth saying it again, but pixel counting is hijacked by digital
camera marketing brochures! For digital cameras they count the total number of
photosensitive cells in the CCD - and they are in groups of 4 with one for red,
two for green and
one for blue. (Don't ask me why - the answer is on the web - somewhere!). For
scanners we count one pixel as being able to represent any colour. So when you
think about a 4megapixel camera compare it to a 16megapixel scan...
For a better explanation and loads of experimental examples, see:
http://www.users.qwest.net/~rnclark/scandetail.htm
And to quote directly from this site: "Film is scanned with each pixel have
a red, green and blue value, so the 3260 x 4472 pixel scan of the 35mm film is
14.6
megapixels. But these are not the same as the pixels in a digital camera. In
a digital camera, each pixel is ony a red, or a green, or a blue pixel. Digital
cameras have 50 0reen, 25% blue and 25% red pixels (thus called RGBG). So a 1
megapixel digital
camera has 1 million red + green + blue pixels. Thus, the 35mm scan has 14.6
* 3 pixels or 43.8 megapixels in digital camera equivalent pixels. "
So, do we have to buy an E-10 yet? Yes, for fun, but keep the OM and the
scanner for serious stuff!
