Colour correcting the Nurse Shark in Antigua
You can see some of the settings I used in Photoshop here to achieve the result (ignore the bottom two layers and know just one of these is your photo OR video)
The layers will be as shown above the first (bottom) 2 but you may get away with fewer - just make sure to have the two shown selected in the images here. Any problems and you can ask me from commenting below. I will help you set up your photoshop files for you.
