Do a sweet picture effect that's quick, easy, and free.
Step 1: Lighting
get a nice spot with a lot of light, and grab a tripod.
(you don't need a tripod, but it helps a lot.)
Step 2: Shutter Speed.
what you need to do is get a long shutter speed, but not too slow or else it will look really blurry.
For the clear picture i had the shutter speed at 8 seconds at F 25
Step 3: Zooming
zoom in, hit the shutter release, when the shutter opens zoom out slowly.
for this picture i did a faster shutter speed
You just need to play with it to get the correct exposure.
