Owners of the rugged Tough TG-4, TG-5, TG-6 or TG-7 can expand the already impressive macro capabilities of this camera specialized in low light and outdoor photography with the FD-1 flash diffuser. The FD-1 distributes the light from the built-in flash to illuminate close-ups evenly. The reflective diffuser allows you to capture even moving subjects without blurring - even at low ISO settings at up to 15 m underwater. The circular FD-1 is ideal for photographing between two and 30cm distance from the lens, with extreme proximity normally preventing the flash from reaching one side of the subject. For ideal control, the FD-1 has a lever to adjust the strength of the flash. By controlling the exposure of the subject in the foreground, the background can be darkened so that the actual subject is highlighted for spectacular effects.
