Why are the Lütschine rafting photos better than GoPro footage?

A professional photographer positioned on the riverbank captures your face and expression at the moment of impact with each rapid, something a helmet-mounted GoPro cannot do. Professional DSLR cameras with fast autofocus lenses eliminate the shutter lag that causes consumer cameras to miss the peak moment. The result is sharp, close images of real reactions rather than wide-angle helmet footage where faces are too small to read. The photographer also knows the river from seasons of experience and finds the positions where light, rapid, and angle align.
