Underwater photography: This is a very narrow market to be involved with. The first issue to contend with is; the professional videographer must be scuba certified. Although the actual shoot employs the same skill set(s) as the on land shooting, the dynamics are hugely different. Equipment set up is dramatically different also. Bracing the camera underwater takes incredible tools and special skills to get the shot and also consider safety issues. Where should you shoot ??, a lake, a river, the open ocean? Just getting to a location can get very expensive. How about the false shoot? What happens when underwater conditions prohibit a good shooting? With the all challenges present on underwater videos the rewards are typically worth it. The finished product is fantastic when conditions are right. The advice here would be if you somehow find an effective underwater dive team that is effective at these complex productions, don’t lose them. The underwater cameraman is a rare breed and very difficult to find. In addition underwater video content is very valuable. Efforts in this area can go on for days to capture a fabulous 20 second video.
