What does cable release do? How to use it? thank you

Both traditional photographers and digital photographers will more or less encounter the camera vibration and skew caused by the excessive instantaneous force of pressing the shutter, which will destroy the integrity of the picture. Cable release is a kind of camera that can control the camera to take pictures, and prevent the camera surface from vibrating and destroying the integrity of the picture.

2 cable release development

The early "pneumatic" cable was just a balloon connected with a catheter, and the remote shutter was pushed by pressing the balloon to achieve the purpose of taking pictures; Although this method is simple and low cost, its reliability is poor. Later, a hollow steel wire cable releaser was developed, which was closely combined with the spiral hole on the shutter of the fuselage, making the performance of the cable releaser more reliable. With the large-scale electronization of traditional cameras, even entering the era of digital cameras, the development of cable releaser is moving from single function to more complex application. Today's cable release not only triggered the shutter; Including long-time photography, interval photography, timing photography, etc. using the B shutter lock function. Even in many indoor photography, in order to avoid the pressure of the model directly facing the camera, many photographers are used to staying away from the camera body, directly guiding the model's movements, and then releasing the cable to capture the instantaneous picture. However, in the case of long exposure and stable photography, for example, cable play is the most useful auxiliary tool for telephoto and macro. Want to meet such diverse needs is not a simple mechanical cable release can bear, but must rely on electronic cable release! Electronic wire release not only includes basic settings: double design of half-press focusing and full-press starting, but also can be further controlled by electronic wire: settings such as operating exposure time and exposure compensation. However, it is annoying that today's electronic cable distribution is incompatible between different brands, even different models of the same brand are not compatible; In addition, it is not easy to obtain the original release in overseas areas outside Japan, and the price is high, which leads to the fact that photographers at this stage generally do not use release as an auxiliary tool.

3 basic operation of electronic cable release

With the function of "two-way button", the electronic cable is released:

Half-time camera realizes focusing/metering.

The camera will take pictures on time.

With the function of "locking door B", the electronic cable is released:

Push and pull the B-door button upward. When the B-door button is locked, the camera will achieve long exposure and focus.

When the key of door B is reset, the shutter closes and the exposure ends.

4 Cable release type

Generally, there are many cable releases in the market, such as "mechanical cable release", "electronic cable release" and "high-end special cable release". This proves that our products are widely used, and almost all photographers will use them. In the camera, the socket for cable release is also different from USB. It can be said that the cable-released connector is the main input port and the only input end of the external auxiliary accessories of the camera in the future.
