One of the many things I envy about painters is that they can include only what they want. I think this is what prompted David Bailey to say: "Compared to photographers, artists have it easy". This got me into a lot of trouble some time ago with a PB member and painter.
I'm fairly sure a painter wouldn't include the collection of toiletries on the left or that bloody irritating sink unit, but a camera captures everything. Unfortunately, I can't paint or draw and I don't like editing bits out of a picture.
I'm pretty sure I misquoted Bailey. This is what I found he said (perhaps it's the revised version after he got into even more trouble than I did):
"Actually, it takes a lot of imagination to be a good photographer. You need less imagination to be a painter, because you can invent things. But in photography everything is so ordinary; it takes a lot of looking before you learn to see the ordinary."
