The last picture in this sequence shows Mabel leaping off the spinning-teepee structure at the playground and launching herself toward some thrilling alternative. Looking at this stop-action picture, I finally felt like the slow painful effort (for non-mechanical me) of learning to use the D-SLR had proved worthwhile. What had driven me to buy the new camera in the first place was frustration over Mabel-in-motion pictures like this one that could only be rendered with the old equipment as an uninformative blur.
