Take a look, if you will, at the 2 images below.  It's pretty clear that, in the second one, the image has been cropped in order to bring the main subjects (the 4 people) closer to the foreground. 

But take a second look.  If that second image has been cropped, surely there should be information missing from the top, bottom and sides.  And yet, count the number of fence posts, say, and you get the same in each picture. So here we have an image in which the main subjects have been brought to the fore, without any loss of visual information.
