Digital BW, The Print

here is a questions for all you commercial photographers.
if a art director ask you to light a subject the way he 
would like it lit, and you are shooting digital from a computer.
you as the hired photographer set up the lights, balance the light
use the right lens for the job. the art director then proceeds to
left click the mouse to fire the shutter. does the art director get
credit for the photography work? does'nt photography by definition
mean the recording of light? i would think the photographer get's 
credit does'nt he. or is the art director a glory hound and wants 
all the credit. i welcome any views. thanx, alex lemus
