Shark Picture before/after: On this picture the shark was too far away so that the flash wasn't strong enough to get the colours. The light has to travel the distance from strobe to fish twice. That's why the shark is cyan and not grey as it should be. With a larger f-stop the sun would have been too bright. With Photoshop camera raw I made a white balance on the shark and enhanced contrast. The colour space of raw images is much higher than non normal JPEG. This is not cheating. A digital raw image is like a classic negative where you can process the colours and contrast while developing positive paper prints.
