A cable release is also known as a remote control. It’s a very useful accessory in photography as it is a flexible piece of cable that has a push-button switch attached or built into one of its ends.
The idea behind the cable release is that you can attach it to your camera and then take the photo by pressing the button on the cable instead of having to push the release button of the camera.
This allows you to be a little more flexible when it comes to taking photos as you can still take them even though you may be sitting 10 feet away from the camera.
When the button is pushed on the cable it will cause a wire running through it to push the camera’s shutter.
This sequence of events can take place because the cable release is attached right over top of the release button on the camera.
Another bonus with the remote control is there is no camera movement because you’re not holding it. This is an ideal way to get rid of camera blur, especially during time exposures.
Some types of cable releases come with built in timers. They can be used with digital and film cameras and wireless remotes are also available.
Some of the cables are available in combination with a tripod. They are ideal to use when you want to take photos of subjects and people that are difficult to get close to. These accessories generally cost between $20 and $100.
