I have an idea for my final piece where I focus around the hiding/camouflage element of the portraits, because I am quite interested in the idea of seeing a picture of the sitter who is trying to hide their idenity. The questions that fly through my mind are why are they hinding? Who are they hiding from? What are they trying to hide? Do they even have something to hide? And so on.
I know that Andy Warhol does some artworks which revolve around the hiding idea in some of his works. I just need to look at more artists, whos' artworks involves the hiding element.
