Climber turns his route into a rainbow

These fascinating images show a climber turning his route into a rainbow as he scales sheer rocks while wearing LED lights.

He records the routes through a series of long exposure images taken from the foot of each rock face.

Luke said: "I wanted to capture the passage of time as I moved up a rock face, flowing from one hold to the next.
