Susan cropped this image square and it’s a good example of getting away from the rectangular 35mm film frame. When most film was in this format, we ended with vertical or horizontal, boring and uniform. So it’s a good idea to experiment with the essential elements and crop accordingly. Which leaves me with the back of head shot. It does evoke a mood and feeling. I think you get a better image with the kids facing the camera. Technically it’s a sound image and if you like it I would not argue.
