This is one of those fleeting moment shots it can pay to be ready for. If your fortunate to have a camera with custom presets like the Canon 5D mark lll or similiar you can program one of the 3 presets ready for action shots like this. I really set it up for quick tracking images of my dogs, so 400-800 ISO, servo-tracking for focus, a wide open F-stop of 2.8 etc. Your settings may vary of course, depending on lenses, personal preference etc. But it can mean the difference of quickly changing from still single shot landscape mode to fast tracking action shots in a single click of the dial. This was shot onboard a foggy ferry crossing of Lake Huron, Ontario.
