(Harris Shutter Effect) Boogie Boarding I

Boogie boarding at the beach. View On Black
The Harris shutter effect combines different color layers from three successive shots to give colored ghosts to moving elements. This series of frames was taken hand-held and required alignment correction (I used Picturewindow pro). Artifacts from the blue layer, though present, are difficult to see except in large size. Alternatively, look here to isolate the Harris shutter effect, removing the beach and sky.
Peruse the Rehoboth Beach Harris shutter effect project.
