Light in Water

Without getting too technical,it is important to know the three things that happen when light hits water refraction, reflection, and absorption.Refraction is the bending of light rays, reflection sends them back in to the atmosphere, and specific wavelengths colors in the visible spectrum are fully absorbed by incremental depths Red is only visible at shallow depths; blue much deeper.Light intensity and individual colors diminish, which forces the underwater photographer to take action in these low light situations.
