Owners of the rugged TOUGH TG-4/TG-5/TG-6 can boost the impressive macro capabilities of this specialist low-light, outdoor camera with the FD-1 flash diffuser. The FD-1 redistributes light from the built-in flash to evenly illuminate close-up subjects. The reflective diffuser makes it possible to capture even moving subjects without blurring – irrespective of low ISO setting – up to 15m underwater. The circular FD-1 is ideal for shooting between two and 30cm from the lens, where extreme proximity would otherwise prevent light from the flash reaching one side of the subject. To ensure perfect control, the FD-1 incorporates a lever for adjusting the strength of the flash. By controlling the exposure of the subject in the foreground, you can darken the background and make the subject stand out – to spectacular effect.
