When I show my photographs taken on a trip, everyone always complains that there are no people in most of those pictures. Upon hearing the same kind of complaint the Master Photographer, Ansel Adams had this to say:

To the complaint, 'There are no people in these photographs,' I respond, 'There are always two people: the photographer and the viewer.'

-Ansel Adams, photographer (1902-1984)

Needless to say, I completely agree with him. :) Thanks to a friend for pointing to this quote.
