Experimenting. Camera on tripod about 6 feet from a planter full of flowers. White flower in upper right corner is centered at one of the viewfinder grid intersections. After each shot, rotate the camera and put the white flower back at the grid intersection (so as to rotate about the white flower in an off center manner). Another multiple exposure (linear movement instead of rotational) is at http://www.pbase.com/ed_k/picture_a_day_2nds

Two more weeks until my ist PAD anniversary.
