When using 2 flash units, there is advantage in that the light reaches to the corner of the image and is distributed evenly, unlike when using a single flash. When using a single flash, the light emitted is strongly centred and may not be distributed evenly to your scene. For high quality photos, a 2-flash system is recommended. When there are floating objects in your scene, set the flash to capture from the side to diminish their appearance. If you wish to photograph without hassle, we recommend using the compact diffuser to achieve even light.
Olympus underwater flash UFL-3 is a new-generation underwater flash equipped with the OLYMPUS RC Flash System. The camera precisely controls the difficult tasks of adjusting light intensity and exposure, and thus makes underwater flash photography much easier. The 2-flash system is also capable of flash fine-tuning (see Screen 1 above) and allows you to concentrate on framing. This helps you to keep the subject in sight.
If you do not have concerns for portability or ease-of-use, a 2 flash system is the recommended method. For professional images, we recommend choosing a 2 flash system.
