What is the difference between graffiti and Street Art

I have seen street artists painting wooden walls but no one tagging

Street Art: Sharrow Vale Road, Sheffield Can graffiti be regarded as street art ever? Does it depend on where it is, artistic value to beholder or materials used? If there is just text text and does that make it graffiti for example tags where people just write their name albeit in a stylised way. Or for example NOP which it has been suggested is a gang name or not for profit. Does it depend on what the intentions of the author is?

Technically street art is art that prior permission has been granted for or has been commissioned. However, some of what is technically graffiti is artistic and on the street so surely that then makes it street art? It can of course be considered vandalism if created without permission. I would not want someone’s name scrawled on my house, so agree with that view in terms of functioning buildings. But there are spaces where it seems relatively harmless like underpasses and wooden boards around building sites. I say relatively for example, compared to the vandalism for example of putting bricks through bus shelters, I really do not understand.

This article  makes several interesting points about grafiiti and street art including mentions that tagging uses just marker pen or spray whereas street art can use more material such as stenciling, mosaics or even LED light. There is also some great photos of Louieville street art in the post.

An example of an UK artist that uses stencilling is Banksey.

Banksy in Hull?!!

Or what about, this? Surely a face captured this well, is art? By the way, I love the blog this post has come from; it is all all about street art, so if you want to see some fabulous street art, mostly from Toronto, check it out!
