One of the rules that I have as a photographer is that I don't crop my images. Demanding that I compose the image on the ground glass right the first time ensures that I give each image my complete focus, and it ensures that I find new compositions that force me out of my comfort zone.
This is the one image where I break that rule. I composed the image with my 8X10 camera and realized while looking through the ground glass that it was better as a 5X7. Rather than taking the time to switch the camera back and the film, I took the shot, print it as a contact print, and trim the print. It works. Sadly, the rocks are no longer there.
