581 I have been wanting to ask this for a long time..it seems straight forward but I am hoping there is a 'rule' that would help me. (Edit..help me to perceive..I am not looking for shooting rules to make a strong photo or anything like that..) (When looking at a photograph that is already taken) Is there a way to determine the physical positioning of the camera lens in relationship to his subject? Obviously, some images are easy to determine, but others not so for me. How do you use the horizon, vanishing points, the place where floors and walls converge, etc to know for sure? I guess lens choice affects the 'rules'.. thanks! some with good lines as a point of reference..
