This tutorial explains how to color correct deep-water images for free. There is a free Python script which I will talk about in this post to do it with ease. The script is basically a command line tool that takes an underwater photo and then corrects it colors. It works with videos as well and there is a simple command to quickly correct colors of your own photos or photos that you download from the internet.

If you went for scuba diving or have some under water photos then you know these photos are kind of a bluish or greenish which looks like a filter. But you can remove that filter like color layer from those photos and make them a little brighter. That is what this command line tool does using its unique algorithm. There is just a simple command and then rest of the process is explained below.
