I have just finished a series of video clips from the Lembeh Straits using a Sony A7s, Nauticam housing and my custom 5X lens. A DIY led light integrated macro port plus two RG Blue lights. Here is the first one. I used a saturated grading style as I am interested in bringing out the color and texture. Even aperture at F32, DOF is paper thin. A bit of vignette is added. Hope you will enjoy it.
