Anemone before/after

Anemone before/after: On the dive safari in September 2011 in the Red Sea my TTL flash electronics got damaged due to water leaking into the underwater case. Luckily the camera and lens survived. But for the rest of the safari I couldn't use the flash anymore. On this picture I cut the anemone in the foreground, made white balance on it separately and processed the background to be darker and more blue. With a flash this image would have looked more or less like this.
