Recordings made underwater are tinted green or blue, unless you use a color filter.Paralenz´s patented DCC automatically corrects the colors to match the depth you are at. Paralenz is the first underwater camera with a pressure sensor. It can display real-time depth and temperature as an overlay in your videos and pictures. Color filters must be changed whenever you change depth, and they absorb a lot of the light. Paralenz doesn’t need filters! It gives you all the light and less task-loading.
