You find that you have to do many things, more than just lift up the camera and shoot, and so you get involved in it in a very physical way. You may find that the picture you want to do can only be made from a certain place, and you're not there, so you have to physically go there. And that participation may spur you on to work harder on the thing, . . . because in the physical change of position you start seeing a whole different relationship.
