Art?

In my opinion, to think about the real meaning of art is very complicated. I don’t know much about the art but I like your points about whether your bedroom shelve is art or not. You said in this art exhibition, it is art, but if it’s in your house, does its still art?
I think anything can be a masterpiece of art; it depends on the person who looks at it. The computer experts may think that Apple’s new released notebooks are the art, but many other people may not. The chef may think his food is art, but for other people food is just food. Perhaps if the photographer visited your house and came across your photographs, he would think they were all art. In contrast, if someone who don’t know anything about photographing see you photograph at this art exhibition, he may not think that it’s an art.
I also like your point about whether the picture that has been edited in the computer is art. For me, I think art is a piece of work that shows the artist’s mind and ability. The non-edited photograph shows the artist’s love of beauty of ordinary and natural things, on the other hand, edited photograph may shows that the artist loves to create, and he or she can create anything with just an ordinary picture.
All in all, the works will be art or not is depend on the artist. If the artist not even think that his or her work is art, how can other people look at it as one piece of art?
