This gallery is the latest in my Canon G10 underwater galleries. Here, off the coast of Western Australia, excursions over a three day period were taken to see firstly the famous Whale Sharks and then two days of fabulous scuba diving off Murion Island and Lighthouse bay in the Ningaloo Reef Marine Park. This time, for the diving only, I used the new Sea&Sea YS-110a strobe to enhance the photography. I don't know what would do without it from now on and can highly recommend getting this add-on with a strobe arm.
