It's probably related to the difference between a snapshot and a photograph.
And it comes down to the "intent" of the photographer. Were they just out snapping or were they out trying to say something with their photography.
Probably even the best photographer, on occasion, will "take" a photograph just because it's a pretty picture.
The difference between them, and a snapshooter, is that they know the craft of photography and have the ability to "make" a photography when they want to.
