there must be a photoshop-tool available with the name underwater action.
it´s useable for recolouring overlightet scubashots.
please tell me where the download is.
thank you pc.scubapezi

Can you post a picture, then we'll be better able to see what your problem is, and be able to suggest a way to resolve it.

Check out some of the ideas here (http://www.retouchpro.com/challenges/showgallery.php/cat/629)

Welcome to RetouchPRO!

Here is an Photoshop action that works well on most underwater scenes which have strong blue channels and weak red ones. The stuff is pretty basic and it should work in Elements as well.
