GoPro test in shallow water shooting without red filter. Its much better than with the 'Blurfix 3 SO' red filters which mess up the colorimetry (this filter is in fact designed for image capture at 10 meters of depth). The main difficulty is the camera stabilization during video capture. Next try will be with a stabilizing underwater wings. Unfortunately a significative part of the image is blurred due to condensation. GoPro format : 1080p @ 60 FPS medium angle of view with ProTune. FCP ed., half speed with a little bit of color enhancement and sharpening.
Shots taken during snorkeling in Rangiroa Island (Marquises, French Polynesia).
