Dear Peter,

It's a substantially meaningless term, except perhaps in the long term when you're dead and people say, "Ah! Peter! Now there was an artist..."

There are two criteria for pictures: critical appeal, and sales. Unless you are independently wealthy, the latter is usually to be preferred.

There's actually a free module about it in the Photo School at www.rogerandfrances.com, which you might find interesting or amusing or both.

Cheers,

Roger
