Add frozen object from short exposure frame to long exposure frame

[Ofnuts]

By the way, the photo you show wasn't taken as you think. There are large shadows on the jumper's body, which are a hint that this wasn't taken just with the camera's flash. So either:

• He belongs to some body painting-sect
  
• There was a big flash on the top right
  
• The diver's picture was taken outdoors and Gimp'ed in.
