The photography blog Camera Technica attached a laser to the hotshoe of a Canon 7D with light reflecting of a wall 20 feet away to see just how usual a tripod can be in the photographic process. The video shows a laser point wobbling erratically when the photographer presses the shutter with his finger. The second clip shows the photographer using a remote release, which illustrates the visible cut in the shaking of the camera. However, setting up the camera on a tripod and using the remote release almost negates all of the shaking. Truth in the lesson: for the best photographs, always use a tripod! The Gorillapod is the best investment.
