My son, Tad was the first to see that this empty dock ought to be included in night shots we were taking of Pentwater from the opposite side of Pentwater Lake. I learned long ago, from National Geographic photographer Sam Abell, that compositions with a triangular shape at the base of a picture tend to lead viewers strongly into the scene and provide a stronger sense of depth. Tad was operating more by instinct. He knew the picture felt good. Rules, tips, and guidelines are fine, but feelings are the most important ingredient in making decisions about the quality of a potential picture.
