What is the difference between a handheld camera and an additional cameraman?

With the handheld camera, your tandem master carries the camera on their wrist. This captures the exit, freefall, parachute flight, and landing.

The additional cameraman jumps separately with you from the airplane, flies alongside, and films your freefall from another perspective. They cannot record the parachute flight, only the landing again. Example footage can be found here ((LINK TO VIDEOS)).
