"Thalassophobia, deriving from the Greek words, "Thalassa" (Sea) and "Phobos" (Fear) is the intense fear of deep bodies of water - Such as the oceans"
For a while, I've had this idea of an underwater CGI/VFX animation of an encounter. At first, the idea for this was for a 19th-Century diver to encounter something while on a repair dive in a shallow body of water, but, while working on the idea, the idea moved more towards the encounter of a submarine and something much larger than itself - Which then became this.
The entire project was made over the course of a couple of weeks, using Cinema 4D for the animation, After Effects for the effects/editing, and Premiere Pro for cutting all of it together - with Photoshop for extra bits and pieces.
