Features:
Specially designed for GoPro, for color correction when shooting diving, suitable for tropical waters and blue waters.
Videos or photos taken without filters are too blue or too green.
It is used between 3 meters and 20 meters. There is enough red light in the water above 3 meters, so no filter is needed.
Some wavelengths of light cannot penetrate the water body, so shooting videos underwater will cause the problem of green shoots
