Here are some tips for underwater filming, straight from the experts at AQWA:
1. Don’t Move Suddenly
Refrain from jerking your body. Should be simple, correct? Needless to say, water surrounds your camera, so it ought to be a stable structure. Although the majority of underwater filming is not susceptible to the type of shaking that a handheld camera normally produces, any degree of wobbling can be detrimental to the final footage. Stabilize the housing by keeping it near to your body. If this doesn’t work, a tripod could be another viable option.
Ensure that you direct the camera onto your subject steadily. This should be done for a sufficient time to obtain a clear, usable picture. After you have your subject in position, count to ten in your mind and do not change the camera’s trajectory or zoom settings during that period. A one minute shot filled with small movements, wobbles or zooming does not constitute a usable picture. Moreover, it is all too easy to ruin everything by believing that you have been focused on something for a long time when you don’t actually get much uninterrupted steady footage!
2. Include Some Variety
Video footage is more captivating if it contains a range of shots. Therefore, alongside all the pleasant, still and steady footage, you should also include some that are shot while on the move.
Rehearse panning your camera by turning your waist to direct it to the side, pressing record, then gradually twisting back round to the opposite side. Do not attempt to twist your entire body with your fins, because this will cause further wobbling.
Every time you kick your fins, you make the camera shake for a split second, so aim to pan past or over the subject by doing frog kicks. If you begin strongly enough, you can obtain some good usable footage and coast after every kick.
