Star trail photography is of sort of photography created by consanguinity of earth and stars moves. Since the Earth spins, the stars are not at set sites in the atmosphere but come into view to shift, more or less into the west. The stars appear to go around both the north and south poles in the sky, of which you usually only see one. Stars extremely close to the pole are roughly stationary in the sky, whilst stars closer to the equatorial plane move quite speedy. (wikipedia).

I really love to shoot especially extreme sports such as downhill mountain bike. Here are a few shots of my friends during their training session. All photos taken with a canon Eos 500d + Tokina 11-16mm lense.
