A flashgun designed to clip to the top of the camera on its accessory shoe or to be used off-camera and fired remotely by cable, radio control or infra-red. External flashguns have more power than the camera’s built-in flash and a lot more flexibility in the way you can control and direct the light.
As every keen photographer knows, the camera is just the start. There's a whole raft of photographic accessories designed out there designed to make your photography better, easier or or simpler, so here's a guide to just a few of them.
The old-fashioned way of firing a camera remotely so that you don’t jog the camera by pressing the shutter button. The cable screws into a thread in the shutter release button and you push the plunger on the other end of the cable to fire the shutter. There’s a locking screw to keep the plunger pressed in for long exposures. Cable releases are rarely seen now – most cameras use wireless remote controls – though a few still have threaded shutter buttons.
This is an accessory that attaches to the bottom of some DSLRs and mirrorless cameras. It provides a longer battery life for long periods of shooting and it’s popular with sports and action photographers taking lots of shots in continuous shooting mode. Battery grips often have duplicate controls for shooting with the camera in a vertical position, which also makes them ideal for busy portrait and fashion photographers.
