What we can tell from this photo is that I did not pan with the motion. I kept my camera still. So what setting did I use to get just a little blur, also unrecognizable so that I do not need to get a model release form signed. I used f. 18 at 1/30 of a second. If I would have panned, the bicyclist would have been in focus and the background would have been blurred. Do you have any images like this? If so, please share on my blog. Thanks!
