Get the blue out ...
Posted 30 July 2008 - 05:50 PM
What can you do? Well ... here's a method that can often return significant natural-looking color to your underwater images that have that blue/green cast. This technique works best with images without a lot of water column and lots of colorful stuff. I'm using Photoshop CS3 for this tutorial, but most of the effects are easy to replicate in other editors.
Full tutorial can be found on my blog ... HERE.
Thanks to David for sharing his picture.

2005 tutorial by Denny Tang on using inverted blurred layer:
If there is any red present in the red channel, manually adjusting the levels might help well, quickly and with full control.
If not, you can try to create some kind of red channel, but I have to admit I have no good experience with it yet.
Converting to black and white is sometimes the best option to me.

Seems entirely possible that's where "my" technique was "born". It was described to me in words on the back of a dive boat by another photographer in November of 2006.
