Above: FP 30K SAR BLT. SAR [ act 3.3 ] : director. When you aim your camera at a subject, the results start to speak beyond words available at the time of the making! This is my experience both with motion-picture and still-photography. Related to SAR [ Strategic Alert Running ] , I find it helpful to use a camera to picture the result of a training. It shows aspects that you may need to become aware of, as part of working on improvement of technique and efficiency. I would call it Photo Generated Injury Analysis, or PGIA.
