Scattered Presence Underwater
In the captivating world of underwater photography, one common challenge is dealing with backscatter - the unwanted reflections of light off particles suspended in water, which can result in a hazy, speckled effect in images. However, by employing effective strategies focused on lighting and positioning, photographers can significantly reduce backscatter and enhance image clarity.
One of the key tactics is to position the light source to the side or behind the subject, rather than directly behind the camera. This reduces light reflecting off particles suspended in water, thereby minimizing backscatter. It's crucial to avoid shining the light directly into the camera lens, as this illuminates particles in front of the lens and creates visible scatter spots.
Using strobes with narrow beam angles and adjusting their power to balance with ambient light can help to concentrate light on the subject and reduce illumination of particles in the water. Getting as close as possible to the subject limits the volume of water and suspended particles between the camera and subject, thereby reducing the chance of backscatter.
Experimenting with strobe angles and heights can also optimize illumination and minimize scatter reflections. For instance, positioning the strobe slightly above and in front of the camera can improve lighting conditions. Utilizing natural light effectively, by positioning oneself so the sun is behind or at an angle to you, can further lessen light scattering in the water column.
For compact camera users, an external strobe is the best solution to reduce backscatter. Bringing strobes out wide, away from the port, and lighting the subject with the edge of the cone can improve strobe positioning. Photos should be taken within a few inches of the port, either in macro mode, with a macro lens, or with a fisheye lens.
Beyond lighting and positioning, proper fins, learning the frog-kicking technique, and achieving perfect buoyancy can help in underwater photography. There are resources available on using strobes, the fundamentals of light underwater, underwater camera settings for macro and wide-angle, and editing underwater photos using Photoshop.
By following these techniques and strategies, underwater photographers can create stunning, crystal-clear images that truly showcase the beauty of the underwater world.
