What are the scientific reasons behind the ‘click’ sound in photography?

Camera clicking sounds: a new perspective

When we take a photo, we often hear a distinct ‘click’ sound from the camera. This voice confirms the capture of the photo and tells the person standing in front that the photo has been captured. But have you ever wondered why this sound actually occurs? There is a complex mix of science, technology and legal norms behind it. Let us take detailed information about it.

shutter and mirror sound

In the past, film cameras and early digital cameras would make a ‘clicking’ sound when capturing a photo. This sound was the result of the workings of the mechanical components inside the camera. When a photo was taken, the shutter opened, allowing light to reach the film or sensor and then immediately closed. It was this process that produced that recognizable clicking sound.

Importance of click sound in modern cameras

Many of today’s smartphones use electronic shutters that capture photos digitally without any physical movement. Nevertheless, the shutter sound is audible in these mobile cameras. Often, this sound is not real, but is a software product designed to provide users with a traditional camera experience.

Reason for shutter sound in smartphone

There are two main reasons for clicking sound in smartphones. First, it is a way to tell the user that the photo has been successfully taken, especially when there is poor clarity on the screen. Second, it is to comply with laws related to privacy and security, especially in Japan and South Korea, where smartphone camera shutter sounds are mandatory to prevent someone from surreptitiously taking photos. Therefore, the shutter sound cannot be muted in many phones sold out there.

Can the camera sound be turned off?

In most cases, users can turn off the camera’s clicking sound by setting it to silent mode or changing settings. However, some specific phones, manufactured for regions where privacy laws are strict, do not have this option. These restrictions are put in the phone’s software.

Psychological aspect of click sound

Experts believe that the clicking sound of the camera provides a satisfactory experience to the users. Just as a sound while typing on a keyboard indicates that work is being done, the sound of the shutter reassures users that their photo has been successfully clicked.
