I think we're lucky to see the Ocean at all! Charlene obviously doesn't like jewelry that much, perhaps she needs a "theatrical" setting to be comfortable wearing her magnificent jewels. Totally awesome!
As for "do we need her....", well no, we don't. However, I think it's great that the House of Grimaldi doesn't keep her under lock and key and that Charlene is not timid about "selective exposure." It is done on her terms, not on the terms of a rabid crowd of photographers clamoring for a photo.
I think the photography is beautiful and wouldn't mind doing this kind of thing myself!!!
