How Do SLR Cameras Work?
To truly understand SLR cameras, it’s essential to dive deeper into their inner workings.
The Components Of An SLR Camera
An SLR camera includes several vital components that work together seamlessly:
- Objective Lens: Captures light from the scene and focuses it on the camera’s image sensor (in digital SLRs) or film.
- Reflex Mirror: Reflects light coming through the lens into the viewfinder.
- Optical Viewfinder: Provides a direct optical view of the scene as it appears through the lens.
- Image Sensor or Film: Captures the light to produce an image; in DSLRs, this is a digital sensor, while traditional SLRs use film.
- Shutter: Controls the amount of light that hits the sensor or film, determining exposure.
Capturing An Image: The Process
The image-capturing process in an SLR camera occurs in several steps:
-
Activating the Shutter:
When the shutter button is pressed, the reflex mirror flips up, allowing light to hit the film or sensor. -
Light Exposure:
The light passes through the lens, reaches the image sensor (in DSLRs), or film (in traditional SLRs), and is captured for the designated exposure period. -
Returning to the Viewfinder:
After exposure, the mirror flips back down, and the viewfinder is once again usable to compose the next shot.
