If you are new to high-end photography, you may wonder how do DSLR cameras work. Many of the best digital cameras, after all, are DSLR models, and these cameras boast a unique operating procedure when compared to other types. So why learn how the best DSLR cameras work and what are the essential components? Keep reading to find out.
Before learning how to use a DSLR as a webcam, you need to understand how a DSLR works in the first place. Learning the basics of a DSLR helps you understand what an electronic viewfinder in a digital camera is and more. It also helps you know what to check when buying a used DLSR. Simply put, understanding how your camera works helps you take better photos and helps you understand crucial processes like how to clean a DSLR camera.
Each camera is unique, with a different body and different internal settings, so don’t be afraid to experiment.
DSLR stands for digital single-lens reflex and is a digital offshoot of a standard SLR (single-lens reflex camera.) What does this mean? A DSLR camera, like the SLR before it, uses mirrors and prisms to reflect light from the lens to the image sensor. Here is how that breaks down via each component.
The primary component of a DSLR is a reflex mirror or prism (or both.) These mirrors and prisms reflect light through the optical viewfinder, which allows you to accurately take a photo of the image you are looking at through this viewfinder. Light starts at the lens and then passes to the mirror prism inside of the camera body. The mirror moves when the shutter is released, allowing a path to be opened to the image sensor. The end result? Fantastic photos.
A DSLR’s lens focuses light and magnifies certain properties of the outdoor space, depending on the lens size, shape, and type. The lens sends light to the mirror or prism, which hits the viewfinder and, ultimately, the image sensor. You can swap out a number of different lenses for unique photographic effects.
STAT: The first DSLR camera was made in 1999, and after only a few years of technological improvements, it eventually replaced single-lens reflex cameras. (source)
A camera’s digital image sensor translates the light and related information into an actual photo, which can then be sent to the cloud, a phone, or a computer. The image sensor is largely responsible for the resolution and quality of the image.
