I have never given a reaction on the old discussion if something is art or porn.
I have a simple definition about art (for myself). It has to bring up something in me, provoke me, move me, bring me into action, give ideas, awake emotions, change, etc., etc. Sometimes I see art which I don't like because it's not my taste. But it's still art to some other people I realize. Then I often think of what people said about impressionism in the 19C (let's take Manet..his nudes often judged as decomposing flesh) or about Vincent van Gogh and so many others which now are considered to be outstanding artists.
The same goes for the British photographer
