I noticed that the father was bringing a Nikon gear and keep shooting his children. I was so envy but no courage to pull my gear and shoot them. Get carried by my desire and started a test shot from afar using my 18-200mm lens. They caught me, to my surprise they were so friendly and wanted some more. I let Charlie, the youngest boy to jump off a pedestal and ask my wife to hold my speedlight left off camera. Drag the shutter speed to create blur.
