Yes I have to agree about the White Balance. My weak point for sure I need to wrap my head around that with the GoPro.
The ray - shark encounter happened so fast! Also, if you look at I think the last Grouper shot with his mouth open and look closely there is a lobster in his mouth. The dive master just feed him but unfortunately I didn't get that shot. Another shot that eluded me was the crocodile. Went looked for it twice but it never made an appearance. Argh .......
