This is a very 'quick and dirty' bodge for helping to smooth out handheld shots only using a wooden spoon, rubber band and your smartphone. It's obviously no replacement for proper equipment but helps in a pinch. :)

Step 1: Equipment...

Your smartphone
The largest wooden spoon you can find
A fairly big, strong rubber band

Step 2: Construction Begins!

Step 4:

Step 5:

Step 6: The 'pro' Camera Equipment!

Step 8: I Also Made a Video
