My manager at work, Greg, and his wife, Alicia, are members of the Houston Underwater Photographic Society. He's the guy who own the "L" lens I really want.
They have HUPS meeting every now and then, sometime it's instructional class sometime it's photo shoot session, mostly underwater stuffs. They have a really cool underwater photo shoot session with a few local models at a community pool a few weeks ago. Definitely no easy task but the result is really really impressive and amazing!
This is the video of the underwater photo shoot session. It's taken and edited by Greg. The still pictures in the video is taken by Alicia.
Another HUPS member and professional photographer, Terry Moore, was there too and you can see the photos taken by him HERE.
