The models interact. When I see something that rings true, I guide them in that direction. What remains fascinating is the liquidity of it. A relationship can flow through so many manifestations. It is possible for lovers to be parent and child, best friends, even adversaries.
Roles shift from moment to moment.
Once I put a chair into the pool with the models and the focus turned to power and bondage. I think there's a natural jump when you add the harness of props and possessions to the softness of naked interaction. That's what I look for. I put people together and wait for something to happen. When it does, I follow it and push it along and photograph it.
