When it lacks anything that could be considered art.

IMO, when it is something that I wouldn't let my 15 year-old daughter or son see (if I had either).

I think once the person in shot takes their clothes off. though there are some good, in taste, photographs of naked people but thats because the focus isnt that theyre naked. A photograph becomes pornography when the intent of the photo is sex

The difference between nudity and pornography seems to be interpreted in different ways depending on the person who looks at it. By definition pornography is any sexually explicit writing and/or picture intended to arouse sexual desire. Cultural background differences influence the viewers perspective. Is a nude painting from an ancient brothel acceptable, while its modern equivalent is not? Is the "reasonable person" in 2007 different from their counterpart 30 years earlier? And because something can claim "aesthetic merit" can it be exempted from charges of obscenity? Absolutes are hard to define. Ultimately it's a matter of subtle judgments.

when you have to buy it under cover of darkness, secret it home in a brown paper bag and hide it from your wife in your sock drawer.

The dividing line is very narrow. I would say its how you interpret that matters. There cannot be any strict rules as to what is acceptable and what is not.

I guess that's up to the person viewing it. If it offends you and you find it pornographic then I suppose to you it's pronography. I personaly feel that the photo or painting is done by the artist to be displayed in an art gallary, magazine, etc. , and not sold to a pornography magazine or web site for people to use for their sexual gradification, then it's art.

When explicit sexual acts take place

I think, that when there is some sexual act or close ups of genitals. We have to ask ourselves what was the intention of the person(s) taking the picture or movie, was it to arouse sexually or to provoke interest and conversation?

Pornography and art aren't exclusive concepts. Pornography can very well be considered art.

I think that art is completely subjective. What is considered art to one is pornography to another. I have seen "art" that I found to be offensive and of no value to me whatsoever. Others loved it and thought that it was beautiful. But, I have a feeling the person looking for porn rarely buys art accidentally.

When it involves the sexual interaction of one with another or more when it involves the use of foreign objects and most of all when your mind allows it if you can't see the art you will only see naked people

It becomes porn when it is distastefull and vulgar. If someone looking at it is appreciating it in a 'different' way then you would art then i think this is classed as porn. At 16 i started college and my first lesson was Life Drawing. We were all trying not to laugh, thinking omg this is wrong, but after a few lessons we were able to appreciate the body more, draw it well and not have any sexual feelings towards our media (not worded very well but i think you get me). I now have a qualification in the subject, and loads of work i have no where to put!!

When it's just done for the pupose of getting off...

When it gets sexy.

When you give the Government the power to decide for you.

penatration.... nudity isnt disturbing to me...

when someone with influence declares it so.

The moment you enjoy it so much you start touching yourself in a place where you can enjoy it most. THEN, it is evil, awwffull porn, and you are going to HELLLLL !!!

It's a matter of taste. No pun intended.

When pornography tries to delineate art..!

Never

When there's more wobbly bits than tree's lol ;-)

THERES A BIG DIFFERENCE ON IT TALAGA... ART BECOME A PORNOGRAPHY IF THE ARTIST HIMSELF DRAW OR TAKE A PICTURE OF A NUDE PERSON AND SELL IT... USING IT TO EARN MONEY... AND THATS ALSO AN ART TUNING TO A CRAFT... NOW, HOWS A PORN TURNS TO AN ART... WELL I CAN SAY THAT IF A PERSON WHOSE LOOKING AT IT GIVES A GOOD MEANING TO THAT PICTURE OR DRAWINMG OR ANYTHING WITHOUT GIVING AN AROUSE EMOTION AND INTELLECTUAL MASTURBATION... THATS MY ANSWER AND JUST MY OPINION...

When the camera is in focus???

When the intent of the picture is for sexual purposes with little care for anything else, including the humanity of the subject, it's porn. There's also a sense of the taboo. The worst of it includes sex acts of any kind. In art the subject is not the sexuality of the person, but the sensulaity, innocence, and humaninity of the subject as well as the vulnrability. There's also a big diffrence in the way the subject is posed. In porn the sexual parts of the body are the main focus. They litterly prop them up for that purpose. The rest is just details quickly thrown together. In art you may see the sexual parts, but they are placed further back then the face, legs, and arms. The lines of the body and the face are the true focus with the back and for grounds receiving just as much attention. Another way to tell this is by the lighting. If you look at the lighting in porn it's not focused on the face, but the sexual areas. The light in art is focused on the face primaraly since it is emmotion that is the main focus.

Never

society has been trying to answer that question for years

Porn vs. Nude vs. Art hmmm..... Well isn't it all communication? What changes is your audience.

Pornography: from the anciant greek porné(prostitute)+ grafé(representation). At the time it was easy to see if something was pornographic or not. If there were any nudes and nude women were automaticaly called as prostitutes, than it was pornographic. Today it's not so simple. society is not the same as well the way of thinking. A lot of confusion was made about erotic/pornographic. Erotic is defined as something with good eastetical taste. But art it's not the same, and some artistic photos don't try to reproduce something beautiful. Francis Bacon is an example of this. So, if today's art is not beautiful.., why should erotism be as well, if we want to consider it art?. Forget that definition. By logic, erotism it's all that activate our sexual impulse, and pornography.., it's all that represents nudes in sexual activity. A photo can be erotic (sexual) with no nudity on it. Just by the look of a hand. If there is nudity, it's pornographic. Pornography can be erotic art if the nude is represented into an "artistic" context. If not, if it is only the photo of a nude body just like that, it's porn. The problem here, is to find a new definition for words that keeps the same value as 500 years ago. Saudek has good artistic/erotic photos. And it's pornographic... well, so what! But to say it's only pornographic, well, I pitty the fool.

I believe that pronography exists for the sole purpose of making money from arousal. Art is a form of expression, and nude are is no different. Everyone knows what a human body looks like. Pornography is vulgar, art is expressive, and enlightening. Art becomes pornography when those lines are blurred, and the art itself comes to express nothing but mere sexual arousal. Art makes you think. On the other hand, pornography does not, it makes you react by instinct, mere carnal desire. I'm only 17, and even I can tell the difference. it's a shame that some people are so closet minded that they cannot appreciate nude art. Of course, one must take into account that differnt cultures view nudity differently. For example, those in Arab countries normally have more clothing covering theirbodies, particularly the women. However, in many places in Europe, nudity is commonplace among places like beaches.

when you get sexual arousal from it and you act upon it. or make it for the sole purpose to get someone off.

when nasty Art shows his private parts in public...

W/ penetration. lol

We got into this discussion in my drawing class and the conclusions were that it is pornography based on two things. 1.) The intent of the artist and 2.) The intent of the viewer. And that is why the line seems so fuzzy. While a nude that was painted 100 years ago will likely not be considered pornographic by the viewer, it may have been intended that way when it was first painted. And vice versa. So next time you look at a nude picture you have to think - "Why is the artist showing me this?" and "Why am I still looking at it?" And if either of those is "To get aroused." Then that is what I would define as porn.

any form of 2 (adults)interacting

When it looks sexual. :|

I checked a website for the etymology for the word pornography- Pornographos means writing about prostitutes. So to answer your question, it's whenever a story is about prostitutes.

What is the really seedy detail in the story that Tyneside police staff may have been involved in selling stolen images of Spencer Tunick's artwork that involved 1,500 people standing naked by the Tyne? Not that the pictures have been illegally grabbed from CCTV footage, but the image of them changing hands in a pub. Sell a nude photograph in a gallery shop and you are disseminating art. Move the place of exchange to a grubby north-eastern drinking den (as I picture it) on a dead Sunday afternoon where pictures of naked vicars and traffic wardens are passed between leering boozers and it all becomes much muckier - "pornography", even.

when its meant to get some one off instead of just look beautiful or thoughtful

art can be anything porn comes into it alot as people paint such erotic paintings and people take photos of the human body really even pritning the porn mags art surely?

You'll know it when you see it.

when it gives the Judge an erection

It's the wrong question. Porn is a subcategory of art. And it is that which directly stimulates a fantasy reflex i.e. sex porn: big tits. easy lay, monster cock and about stuff most viewers will never try food porn: cooking shows about stuff most viewers will never try travel porn: exotic locales and about stuff most viewers will never try etc

When the point of the "art piece" or photograph is that it be MASTURBATED to!

When people started fantasizing, corrupting and abusing every inch of the body line to make it pornographically consumable.

in the beginning and the end... human art!

There are so many fetishes out there what isn't considered pornography?

I used to think Playboy Magazine was a prime example of pornography but I would no longer put it in that category. I think pornography has "dirty" intent.

After you slap the Bologna to it.

When it offends the least intelligent among us.

When the message of the art piece is i want sex. Otherwise a art piece that has naked bodys, but with words either painted on the bodies or on a paper, board shown to the public is not consiter pornography.

When one art object is screwing the other art object.
