How come is that multiple ghost image? What causes that?? I don't have a good enough technical explanation to it myself. But, I have never seen such an image for a moving object shot in similar conditions since I shot digital back to 2001. Since that, I guess I have already shot about 70k+ digital images with all my DSLRs/DCs - but never seen such irregularity. Really Strange and Weird, I have to say!
