This pic was taken on a trip to Malaga in Spain. On the picture you see my friend and I (A jugglingduo named Jugglish).
CD-light
In this picture I used a cd, covered with small water drops. Then I used slow shutter speed in manual mode, and waved with some lights in a circle.
Guitar shadow
In this picture I slowed down the shutterspeed on my camera ( Finepix HS20 EXR) and turned of the light in my room.
Then I took a light and just waved it around behind my electric guitar, and “Voila”.
