I took this shot of a walker passing me on the sidewalk, shooting with the camera held by my side. The details are E-P3, 12mm lens, ISO200, 1/6 sec @ f/2.8. The only processing is a curves adjustment in Aperture to recover highlights and add a very little amount of contrast. I expected motion blur due to the length of the exposure since both the person and I were moving in opposite directions. I didn't expect what I've got. Apart from a right leg and arm the person has disappeared and there's a funny, very clear white image just to the right of the person just above wrist level. I have no idea of what that is or how or why most of the person disappeared. The only think I can think of is flare since the sun was setting somewhere on the other side of the fence (the horizon is below fence top level). Really weird effect. Explanations welcomed.
