CREATING CIRCLES

THERE ARE DIFFERENT WAYS TO CREATE CIRCLES WITH LIGHTPAiNTING.

‚Äč

THE EASIEST WAY IS TO WORK WITH HAND-SPINNING A TUBE OR A BLACK STRING AND AN ATTACHED LIGHTBULP ON ONE END OF IT.

THIS CIRCLING METHOD CREATES AN ALMOST ROUND SHAPE IN 2D OR WHEN YOU ROTATE THE SPINNING STRING YOU WILL GET AN ORB. 

THIS IS THE COMMON METHOD TO CREATE ORBS OR TO SPIN STEEL WOOL.

IN THIS TUTORIAL I WILL SHOW YOU A DIFFERENT SETUP, THAT ALLOWS YOU TO CREATE MULTIPLE EXACT CIRCLES IN ONE PICTURE.

 

THE METHOD IS EASY, ALL YOU NEED IS AN OLD BIKE WHEEL WITH ITS AXIS CLAMPED ON A TRIPOD (FOR THE MOBILE VERSION) OR A FIXED MOUNTING ON A WALL.

 

TO CREATE MULTIPLE CIRCLES IN ONE PIC YOU WILL USE THE SAME SETUP SEVERAL TIMES. PLACE THE "WHEEL-TRIPOD" IN YOUR SETUP AND TAKE THE FOCUS SETTING FIRST. NOW SWITCH ON YOUR LIGHTSOURCE ON THE WHEEL AND LET IT SPIN.

 

NOW IF YOU WANT TO CREATE MULTIPLE CIRCLES, JUST CLOSE THE LENSCAP IN BETWEEN, REPLACE THE TRIPOD TO A DIFFERENT POSITION AND OPEN THE LENSCAP AGAIN. DEPENDING ON THE DISTANCE SETTINGS OF THE "WHEEL-TRIPOD" TOWARDS THE LENS, THE CIRCLES WILL APPEAR SMALLER OR BIGGER WITHIN THE PICTURE. 

IF YOU WANT A CIRCLE TO MOVE UPWARDS LIKE IN THE PICTURE BELOW, YOU NEED A TRIPOD WITH A HEIGHT-CONTROL WHEEL FOR THE CENTER POLL WHICH YOU HAVE TO SPIN SLOWLY FROM THE BACKSIDE WHILE THE WHEEL ROTATES. 

YOU CAN USE THIS WITH LEDs ATTACHED ON THE SPOKES OR RIM OR WITH TABLE FIRECRACKERS (WHICH SHOULD FACE TO THE OUTSIDE ONLY), SPARKLERS AND LIGHTSWORDS WOULD ALSO WORK FINE.

 

 

WHAT YOU NEED:

 

- 1 BIKE WHEEL WITHOUT TIRE (A BMX 20" SIZED WHEEL WORKS BEST, OTHERWISE THE WHEEL WILL TOUCH THE TRIPOD IN ITS LOWER PART)

  YOU MIGHT NEED AN AXIS-EXTENSION NUT TO CREATE THE NEEDED DISTANCE AND A CLAMP ON THE TRIPODS MOUNTING TOP)

- 1 BLACK SPRAYCAN (MATTE)

- SPRAY THE WHEEL BLACK

- 1 TRIPOD (IDEALLY MATTE BLACK SO IT DISAPPEARS COMPLETLY WITHIN THE PICTURE) TO CREATE UP- OR DOWNWARDS MOVEMENTS THE     TRIPOD NEEDS A ROTOR-WHEEL FOR CHANGING THE CENTER HEIGHT POLL 

- BLACK CABLE TIES TO FIX YOUR LIGHTSOURCES ON THE WHEEL

- LIGHTSOURCES OF YOUR CHOICE
