On a recent trip, I was asked to take a photo of someone using their phone against the stunning backdrop of the Appalachian Mountains. Afterwards, I requested they take a picture of my girlfriend and me with my camera. After ensuring the camera strap was securely around their neck, I handed them the camera. Their immediate question was, “How do I look through it?”
Instructing them to use the viewfinder, they seemed puzzled about how to capture the photo. This led to the question, “What’s the shutter button?” It dawned on me that the concept of a shutter button is alien to many who have only used phone cameras, which lack physical shutters and shutter buttons.
The shutter button is a tangible button on traditional cameras. When pressed, it completes an electrical circuit, signaling the camera’s microcontroller to activate the shutter and capture an image. This process might be unfamiliar to many who are accustomed only to touchscreen-based phone cameras.
Surprisingly, not everyone knows what a shutter button is, despite the ubiquity of camera phones. A shutter button is not just a simple mechanism; in autofocus cameras, it often serves a dual purpose. For example, in Canon’s autofocus cameras, lightly pressing the button activates the autofocus system, a feature known as “half-pressing.” A further press, with a noticeable click, then triggers the shutter.
In contrast, cellphones don’t have a mechanical shutter or a physical button. What is often called a button on a phone’s screen is merely a virtual representation, a simulacra as described by Baudrillard. Simulacra are digital representations that mimic real-world objects, like camera buttons, creating an interface that simulates using a physical camera.
Simulacra are not exclusive to phones; they’re part of all graphical user interfaces. Their design relies on our understanding of the physical world, making digital devices accessible to those familiar with their real-world counterparts.
While it may seem trivial, the tactile feedback and control offered by a real shutter button are hard to match with a cellphone’s touchscreen, especially when trying to capture fleeting moments quickly and reliably. The physical shutter button’s straightforwardness and responsiveness are unmatched in the world of smartphone photography.
