[Thoughts] My Photoshop secret tip for underwater photography post-prod

The photo as taken with my now very old (but still working) Powershot A70 in its underwater case ($100 on ebay) :

Blurry and lacking some colors, isn't it ?

This is the photoshoped result.

Before...

After...

So you are in Photoshop and you opened your photo (it's called Background by default).

1 - Duplicate current layer (Background)
2 - Auto Levels
3 - Brightness/Contrast : Brightness +50
4 - Duplicate Background
5 - Move current layer to layer 2 (at the top)
6 - Auto Color
7 - Opacity 80%

If the result is too flashy you can play with the Opacity of the two first layers.

Of course you can make this an action script.

Enjoy!
