It always amazes me what a big impact inches of difference can have with point of view. With this Montana barn, I moved this way and that, sidling a foot to the right and left. It wasn't just getting the llama unobscured-- there was a difference in sensing the scale and shape of the barn depending on how much of the end in shadow was included. It was also crucial to let the mass of the building "rest" in the frame...giving proportion to the sky, horizon and ground. Microadjustments of the camera...snap.
