This instructional video shows you how to build your own stabilizer in 5 minutes for less than $1. It is super light weight and folds up small enough to fit in your pocket. With this stabilizer, you can hand-hold your camera with shutter speeds at least 3 stops slower than without. It works just as well with video camera
Wow. Seriously, that's the first time I've ever seen one of those videos that was actually practical and realistic!
