You're quite right, Thomas. This is now the norm because it's so easy 
to strip the colour out in Photoshop and still retain the densities 
needed to print as a full tone B&W image - if done properly. But few 
people do this because it takes real skill to get rich, open shadow 
detail using a single ink (black) on an offset press. B&W pictures in 
art books, monographs etc., are usually printed as duotones (black 
and a second colour, often grey, to retain highlight detail and 
enrich the lower mid-tones) to overcome this. What you may not be 
aware of is that nearly all B&W images in magazines are printed using 
CMYK process inks, i.e. they are really colour! Examine the 
characteristic rosettes under a loupe and you'll see it clearly.
Nick.
