Had a great time taking pics of a Green Sea Turtle at Kua Bay Beach on the Big Island of Hawaii. They are almost always grazing on the sea grass that is covering the underwater lava rocks. The turtles just hang in the waves getting beaten up on the rocks like it is no big deal to them.
I used the SPL housing for my 5D Mark IV on this shoot with the EF 16-35mm 2.8L III USM lens. At 25mm with ISO 800, f/10 & 1/1000
My favorite pic from shooting. Here are the rest of the photo I shot.
