Contrast is another primary element for underwater photography that usually requires retouching. Follow this simple Photoshop technique to enhance the contrast of the distance without affecting the foreground.

Open the Layers> New Adjustment Layer menu and select Brightness/Contrast. The Brightness/Contrast tool should appear. In the Brightness/Contrast tool, increase the contrast until the distance looks correct.

Click on the thumbnail of the the Brightness/Contrast layer mask. There should be a white outline around the layer masks thumbnail when activated. Select the Eraser tool from the tools pallet. Right mouse click anywhere on the document window to open the brush options and set the hardness to 50. Now, erase the foreground area. The area you erase should appear black in the layer mask thumbnail.

Rollover the image to see the before and after effect.
