Freelensing

"While perusing the Internet for new photography techniques, I came across something referred to as “freelensing”. This technique is achieved by detaching the lens from the camera but holding it in place, then shifting the lens around to focus the shot. Shafts of light are “leaked” into the image, a high degree of bokeh is achieved (since the aperture is effectively at “0″), and one can capture extreme macro shots. This technique also somewhat demonstrates the principles of tilt-shift photography, where the plane of focus and the line of sight are no longer parallel to one another - basically, objects that are at different physical distances from the camera can all be in sharp focus if they lie on a straight line."
