“The photographer should suffer, not the audience.” is what Danny Rubinstein once said. I guess he was, amongst other things, referring to the suffer when changing the perspective, e.g. laying down on the ground.
So it is a good thing when you can put the camera on the ground (or anywhere else) and take a whole new perspective without having to lay down. How many pictures have you “missed” because you wouldn’t lay down on the floor?
