As I wandered around Lake Kittamaqundi there were numerous places to stop and contemplate, and this was one. I set up the 8×10″ pinhole camera and composed for the lightly moving branches and shadows, opening up to reveal the lake. Following the exposure I decided to next concentrate on the small cloud. I reset the camera, pulled the dark slide, and just before starting the exposure I realized that the small cloud was no longer there.
Sometimes that is just how it works.
