What Is A DSLR Camera And How It Works?

DSLR Camera

According to Panasonic India CEO and President, Manish Sharma, the DSLR market in India accounts for approximately Rs.2,000 crore of the camera revenue today. Before you decide to purchase your camera from, it is necessary to understand what is a DSLR and the mechanics behind such devices.

DSLR refers to a digital single-lens reflex camera. Such devices combine two distinct technologies to produce high-quality pictures. The first technology controls your camera’s shutter functionality, while the other technology is responsible for capturing a recorded image digitally, rather than on a film.

  • Nikon was the first brand to introduce DSLR cameras for consumers in 1988.

Several parts of the DSLR camera function together to form quality images. For instance, a viewfinder, lens, shutter release, mode dial and many other instruments of this device must operate flawlessly to click pristine pictures.

How a DSLR camera works?

All DSLR cameras’ functionality can be divided into three vital steps. They include

  1. Light capture.
  2. Reflex using a single-lens.
  3. Receiving an image using the digital sensor.

Light capture

The key to understanding how a DSLR works, lies in understanding how cameras manipulate light. As light reflects off a subject, it travels to an observer looking through the camera. If this reflection enters through a small enough aperture in the camera, it leads to the formation of an image on the other side.

As a photographer, you can manipulate the camera lens to bring this image into focus. The distance of a picture behind the opening changes as you alter the focus.

Reflex using a single-lens

The camera operator needs to understand what the subject looks like before clicking an image. As the DSLR camera full form indicates, this device relies on a single-lens reflex system. It uses a viewfinder to showcase a particular image to an operator.

By using a mirror in front of the camera sensor, the image is reflected upward into a prism. This prism ejects the image onto the viewfinder. While capturing this image, the reflecting mirror flips out of the way. It leaves enough space for the shutter curtains to move, allowing light to strike your camera’s sensor and create a photo.

  • Sony released the first DSLRs capable of 3D photography in 2010.

These cameras are costly equipment, making them a considerable financial burden to replace in the event of damage or loss. Bajaj Finserv offers DSLR Camera Insurance policy under its Pocket Insurance & Subscriptions. This cover can significantly reduce your financial liability in the event of accidental damage to your beloved camera.

Receiving the image using the digital sensor

The sensor is an essential part of your camera. It is responsible for the final quality of your captured image. The millions of pixels on the sensor are extremely sensitive to light. When photons from the outside image fall on a camera sensor, it causes the pixels to release electrons.

The resulting charge depends on the intensity of the photons. This is how the camera duplicates realistic lighting in the recorded image. Areas, where the maximum photons strike, is illuminated more in the final picture.

  • According to a 2014 survey, you are most likely to experience camera theft when the gear is inside your vehicle.

Advantages of using a DSLR camera for photography

Now that you know DSLR long form along with its working process, you must ask yourself why to choose this kind of a camera.

Listed below are some advantages that should help you making up your mind –

  1. No need to rely on film – Perhaps the most significant advantage of DSLRs over ordinary cameras is that it is digital. You do not require a film to click pictures using such a device. Moreover, since no film is needed, you can capture images as long as your memory card has available space in it.
  2. Greater customisation –As a camera operator, you are free to set the colour balance, ISO speeds, flash outputs, temperature and all other aspects of an image as per your preference. This greater freedom is often desirable, especially for professional photographers.If you are interested in photo editing software, take a look at for the latest tips about how to use photo editing software.
  3. Higher quality pictures – An increased sensor size of DSLR cameras ensure crisp and clear images, which make these devices apt for professionals.

If you own such a camera, ensure you avail proper DSLR camera insurance policy right after purchasing the gear. Photographers also possess additional electronic equipment of some worth. Purchasing insurance policies such as an electronic stationary insurance plan can help reduce the financial liabilities resulting from damage or loss to these items.
