I shot the last frame, wound the roll, and opened up the camera to load another roll of film into the camera. As I opened the back of the camera, the roll of film started to unwound creating a gap between the plastic reel and the film. I instantly knew that light had ruined part of the film. I developed the film hoping the entire reel was not effected. My hope was rewarded and I only lost 5 frames due to the light leak. I actually enjoy how the light leak isolated the man standing at the far end of the train platform. A beautiful mistake at the cost of a few frames.
