Had some fun with camera blur (as opposed to motion blur). I set the shutter speed to a slow value like 2 seconds. Took several pictures. During the exposure, rotated (spinning) the camera wildly. Following are some of the shots.
With practice I learned to keep the camera still at the end of the exposure to get a relatively sharp scene.
A little more time given to the still part.
And you can start with a still motion followed by spin and end with a still to get two sharper images.
And the funny part is that the camera sensor with keeps track of the orientation (portrait or landscape) was totally confused.
I had lots of fun. hope you enjoy.
