Photographer Mark Tipple is onto something really cool with "The Underwater Project."
Mark considers himself to be a documentary photographer.
The purpose of this project is to document Australia's relationship with the ocean.
(Or something like that.)
Personally, I just think these photos are really cool to look at.
I'm loving the crashing waves and the swimmers expressions.
Mark said, "I've always been intrigued by what happens below the surface, like what's happening where we can't see."
Here are a few of my favorite shots.
