Hello, I recently bought RX100 and this is my first camera of my life. I am a complete newbie. After few hours of fiddling I do know basic functions of RX100 but I'd like to know if it is possible to take this type of picture from RX100: http://www.flickr.com/photos/sakshiparikh-photography/6932330707/in/photostream As you can see, the man is fully visible but the background is blur and leaves motion trail. If yes, then could you please suggest how? Thanks!
