Hi! I am an underwater photographer specialising in shooting still photos. You can see my proper work on my website (google me if interested).
But I dabble with video shooting. I mainly use Vimeo for uploading test videos and time-lapse sequences. They are usually underwater or at least water related. Video are time-lapse are skills I want to develop and there is no better way that practicing. I also review quite a lot of camera gear for underwater photography and I also use this account for sharing test videos from those cameras.
To save space I usually do not upload videos at HD.
