Powder turn
Action sports, slow motion: the snowboarder carves a deep turn through fresh powder, a huge backlit spray of snow arcs off the board and drifts down glittering in the sun, the rider stays whole and in frame, smooth telephoto tracking shot. Realistic motion.

The camera tracks low and parallel to the ground alongside the lone rider as the horse gallops steadily across the immense white salt flat, a long plume of golden dust trailing behind and drifting in the wind, the long shadow racing across the cracked salt, distant blue mountains holding still on the horizon. Warm late sun, smooth stabilized tracking, 65mm film look, natural horse gait." } }'
