You can basically break art down into two things: Technical skill Concept value
I'd definitely concede that porn can be art. And technically it may even be superb. But the concept is always going to be terrible, because it's the least original subject matter since the dawn of time. It exists for the genitalia and not the mind.
And yes, this is why I'm not too fond of even the most brilliantly conceptual modern art... it's basically the reverse problem of porn.
Please stop. I'm so tired of hearing "art is subjective" and "art" is what ever each individual out of 7 billion human beings wants it to be. Stop trying to force every hobby in the universe that has to do with imagery into the word 'art'. Let porn be porn and quit trying to call it art. What's the point. It doesn't elevate porn. It doesn't make porn more likeable. It doesn't cure world hunger. It's just stupid
I've never been to art school or anything, and my knowledge of art comes from a couple years of high school art classes, so all I'm really judging from here is my own instinct of what looks good and what doesn't. Sorry if I'm way off base when I say this but...
I'm pretty sure that there's a pretty distinct line between Artistic Nude and porn.
This is porn:
This is art:
At least for me it's pretty easy to tell the difference between a piece of art and a crappy digital camera shot of a couple of slutty chicks with self respect issues. But, then again, I'm no real artist so I might be way off base.
