Underwater Video Recording
Formerly it was difficult to record underwater video, basically because the underwater video camera housings had a prohibitive price for the economy of many, and unless you were a passionate amateur videographer.
What we are going to deal with today is a series of tips and recommendations for the moment when we go to the water with your cameras and be able to do things in the best possible way.
Diving technique filming
One very important thing is to control our buoyancy at the moment we are recording. Just as they tell us that talking on the phone at the wheel can cause us to suffer distractions and have an accident when we record we have our attention in other things and we can change our depth without hardly realizing it. And we already know what that can cause us.
The underwater cameras have always had a hold for both hands. This is how the documentaries and the scenes of the films are recorded underwater. The movements of the camera must be very smooth to prevent the image from shaking. You have to move slowly to where you want to go.
When we want to record a fish or an approaching diver, it is better than it is he who enters the field of vision of the camera, better than if we look for it. Once inside the frame, we can move towards it.
Configuration of the camera
Clean the lens of the camera and the underwater camera housing before inside. Yes, this is the most important, then, if not, absolutely everything we record will come out with spots and will spoil both the photos and the videos.
The first thing we must do before getting into the water is to make sure that it is well closed. Most digital cameras usually come with image stabilization. It is advisable to have it on although we will not stop holding the camera firmly. In the underwater housing condensation usually occurs inside them due to changes in temperature. To avoid this, we can introduce wipes or paper or even silica gel (if there is space) to avoid this effect.
As you descend into water the properties of light vary.
There are many factors that affect it, depending on the light itself and the water conditions, and the different wavelengths that form the colours of the rainbow are absorbed differently, so we will quickly start to lose certain colours. Therefore, at a certain depth, the use of lighting torches is almost indispensable for certain types of photos.
The recording speed depends on water clarity, if we dive in waters with low light as is often the Cantabrian, we recommend a low-speed recording of 30 frames (frames) per second, as having less light the “film needs more light to achieve a good exposure. If we dive in places with lots of light and clarity in the water, we can increase this speed to get more fluidity in the image.
If we talk about the resolution, this should not be very high (1080p or 720p at the most).
The resolutions of HD, FULL HD, 2K, 4K are great, but they need good light to work and they require that the computers with which we make the editing of the videos are very powerful. If you have normal equipment or plan to edit from tablets or phones a low resolution will give you better results (if your intention is to share your videos via WhatsApp with more reason).
A tip from an expert underwater videographer: if you have more than one battery, always take them and make sure they are always charged, when you do successive dives, you change them when you go to do the second dive since the cold water shortens the duration from the same.
