Mechanisms that allow photographers to capture pictures from a distance are referred to as cable releases. These devices can be found placed on top of a professional tripod. The cable release is actually type of a wire attached to the camera which features a button trigger at the end. while clicking the photograph, the user just presses the button at the end which in turn triggers the shutter of the camera to click the photograph.

This device is especially useful for taking pictures which require exposure to light for a longer period of time. For this, it is essential for the camera shutter to be kept open longer and the cameraman to stay focused and steady through the process. In such cases, when there is a requirement for the user to stay unwavering for a long duration, he or she can take the help of a cable release and tripod, like the Velbon Sherpa 550 R, to eliminate any risk of shaking. When photographs have to be taken in dim lighting conditions, when photographs have to be taken at a very close range or when a portrait photograph has to be clicked, photographers find it easier working with a tripod and the cable camera release mechanism.

Cable releases can be used with almost any model camera and also come in remote controlled models. Traditional cable release can be used with the traditional cameras that are operated manually. Digital cameras however require digital cable releases. In order to prevent any risky or unintentional shot, the cable camera release can be locked with a locking mechanism when not in use.
