If you ever wanted to film a video that shows your hands handling something (i.e. gadget video review), here is a great example on how to achieve the perfect 90 degree camera angle so the only thing filmed is your hands. What you need is to pull out the center pipe of the tripod, on which the head of the tripod sits, and reinsert it from the bottom up. Then you just need to adjust the angle on the tripod head (depending on the model you use, Slik video tripod works best) for the camcorder lens to point vertically downward (see the photo below).
