Digital BW, The Print

True, no question that a high quality scan of a well exposed 4x5 
negative can produce much larger images and prints, but I was not 
talking about the theoretical MP equivalence of 4x5 .  I said that if 
one wanted to make images with a single shot digital camera suitable 
for producing images with the same quality as the images I obtained 
with the 4x5 and the stitched 10D, which were both designed to be 
printed at approximately 16x20 inches at 360 ppi, then you would need a 
40 MP digital camera.
