What is a DSLR camera?
DSLR stands for Digital Single Lens Reflex, which is a highly popular type of camera at the present time. Many people who are not familiar with cameras believe that DSLR encompasses all types of professional/semi-professional cameras with interchangeable lenses. In reality, DSLR is a specific type of camera that utilizes the mechanism of single-lens reflex and digital sensor.
How does a DSLR camera work?
Light directly enters the lens, hits the mirror, and reflects onto the pentaprism, which is adjusted and continues to reflect to display the image received in the viewfinder. When pressing the shutter button halfway, the mirror flips up, the shutter opens to allow light to reach the sensor. Pressing the shutter button completely, the mirror returns, the shutter closes to end the exposure process. The speed of the mirror and shutter is very fast, up to 1/4000 – 1/80000 second.
