The Foto&Tech RC-6 Wireless Remote Control (Infrared) is a simple, compact, infrared remote control that makes it possible to fire a camera wirelessly from as far as 16 feet. It is recommended for taking pictures of subjects that are difficult to approach, or to minimize vibration for close-ups and time exposure, and it is powered by a CR-2025 3v battery (included). The FTRC-6 supports the bulb exposure camera setting making it a worthwhile accessory for shooting long time exposures for low-light photography or unusual daylight effects.
