The first tests in the swimming pool in warm sunlight in which I filmed my daughters when jumping from the 3-meter tower at 720p and 120 fps, also brought very good results, which could be processed into beautiful slow motion movies. I kept doing the Ghost-S in hand, controlled the image area in the built-in display and appeared simultaneously with the branch history, the camera into the water, so that the jump in a single take in a shared air and water absorption.
However, I was not satisfied from the outset with the performance mountain biking in the forest. Here the ghost-S, even at low frame rates, only quite muddy recordings managed. That may have located where, caused by the trees low light.
After few days later the drift Ghost-S, adopted during a motorcycle tour of your mount from Nirvana, I once again made an attempt with the GoPro and a chest strap. The recordings were much better!
In my opinion, this GoPro has a much better Lowlight-capacity, as the Ghost-S.
