DSLR working principles
- Light enters the camera through the prism and strikes the reflex mirror.
- The reflex mirror reflects light vertically upwards to the focusing screen.
- Light travels through the focusing display and reaches the pentaprism glass block.
- The pentaprism directs light to the viewfinder after focusing it with two distinct mirrors.
- The viewfinder provides a live image preview to the viewer.
- The reflex mirror now flips upward when the shutter button is pressed, preventing the vertical light channel from directing light directly into the image sensor.
- The shutter will then open, allowing light to reach the picture sensor.
