Crop.
How much merit does this statement carry?
And if this statement does carry significant merit, why do we have cameras like the 1dsmkIII and the 5dmkII?
(the reason behind this post stems from a friend who has had numerous college-level photography courses which have instructors (presumably film) who insist that cropping is cheating)

That is the most un-realistic thing. Everybody crops and PP photos...that is the way it is.
What does this have to so with the business of photography anyway?
