ImprovingUnderwater Photography: Lighting Techniques

A great underwater picture should catch the eye of the observer. That might be a vibrant gorgonian, a historic wreck, or a hypnotic reef. Accurate colours depend on white balance, particularly in relation to aquatic creatures that might merge into their surroundings. Filters can also assist to bring back lost colours absorbed by water.

Natural Illuminating Agent

Though the foundation of every marine photographer's toolset is a good camera, knowledge of the special qualities of light will significantly enhance your output. Because of its higher density, light acts differently underwater than on land; knowledge of these variations can help you to better control your photos. Since various wavelengths are absorbed faster than others, underwater photographers must deal mostly with colour loss. This is therefore especially crucial to have a strong supply of coloured filters and external artificial lighting including underwater strobes in your toolkit. Strobes provide daylight-balanced light that recovers lost colours, sharpens contrast and maintains scene details by means of which they When shooting things like big marine life or piers, they also help to create a more dramatic silhouette and cover shadows. Just be sure to properly control the brightness of your lighting to prevent overxposing your subject and degrading the photograph.

Synthetic Light

Artificial illumination will help your underwater photos when natural light is not accessible. Dive lights and strobes—flashes—can restore lost colour and light up marine life to highlight the actual beauty of these species and surroundings. Using these techniques, however, carries extra difficulties and hazards include excessive subject exposure or severe shadow generation. Furthermore, great management of these tools' brightness helps to prevent harm to the reef or disturbance of marine life. Experiment with your strobe's beam angle when photographing a coral reef or sea life. This might change the texture of your subject, therefore stressing some features and softening others. Generally speaking, shooting upward helps produce more pleasing photos and also lessens backscatter. This is thus because, relative to downward or side illumination, the water reflects less upward light. When the light source is close to your camera, this effect is quite obvious.

BackScatter

In the realm of underwater photography, the word backscatter is virtually a curse word; it can be challenging to eliminate in post-production. Still, occasionally it can accentuate the visual and produce an emotional response. Often it can give the picture more depth and is visible in photographs taken in low light levels. Reducing the impacts of backscatter depends on using a neutral buoyancy approach. This will help to lower the silt level in the water capable of reflecting light from your strobes. Additionally beneficial is keeping your camera at the proper distance from your subject. The lens you are using and the power of your strobes will define this; the easiest approach to find this is to divide your maximum focusing distance by the strobe power. This will help you to approximate the lowest strobe-to---subject distance that is feasible.

Colours

A great, addictive and very difficult hobby that will elevate your diving is underwater photography. Although it's a terrific feeling and evidence of your hard work to capture that gliding manta ray or highlight the electric colours of a stunning nudibranch, occasionally it can be challenging to get your images as excellent as you would like them. Underwater shooting presents a major colour problem. Acting as a blue filter, the water reduces greens and absorbs reds. Photographs produced thus may seem dull and dirty. One can benefit by using a custom white balance and RAW photography. Apart from these lighting approaches, one should make use of sophisticated editing tools as Adobe Premiere or DaVinci Resolve (videography) and Lightroom or Capture One Pro (photography). These programmes let you add creative effects like tilt shift and slow motion and help you to lessen motion blur and shiness. Using these tools will also help you to improve post-production editing efficiency.
