Cheapest and most easy Steadycam for everybody.

Step 2 Make the "steadycam"

Mount the camera to the tripod. Then extend the upper part of your tripod, so you got a "grip".
Spread all three legs (at least two) ans extend the third one to a comfortable length (but not too short.)
Take it losely in your hand, so that it moves soft, but does not slip.
See an example in the picture.

Yeah that's it. Move your camera around.
