The intent is completely different. What if the result is an excellent shot? Certainly said photo can stand alone. Not needing a D2X or 20 years experience.
If a shot is 'excellent' by accident it does not make the Photographer good, only lucky.
One of the keys is 'repeatability'.
Art starts with an idea and is then a process of hard work, technique and skill to make that idea real.
You can get people who have original and wonderful ideas but who do not have the technical skill or knowledge to make it work.
You can have people with great technical expertise and control but who have no original ideas.
Both can and do produce Art.
Then you have the rare case of someone who combines both - and you get (for want of a better cliche) Great Art.
Looking at, and understanding, any kind of Art requires the viewer to appreciate both idea and technique in a work so that they can sort out the three different scenarios.
But it is also important to be aware of personal taste.
Liking something does not automatically make it Art, in the same way that disliking something doesn't make it trash.
Beauty and Art are two separate things.
And if no one aspired to making 'Great Art' - and anyone can aspire to this - then no-one would produce anything at all.
