If you’re new to cameras and are considering a career in film or video production, you’ve undoubtedly heard the term “DSLR camera” a lot. What does this imply? And why am I bothering?

DSLR stands for digital single-lens reflex cameras. By utilizing a single lens, these devices are supposed to resemble typical SLR cameras. Additionally, they have several unique characteristics, like interchangeable lenses, high-quality picture sensors, and quick focusing.

Due to their versatility, adaptability, and ease of use, DSLRs are excellent tools for both amateur and professional photographers. Additionally, they are quite affordable in comparison to other types of cameras.

What is DSLR?

Note : A DSLR Camera (Digital Single Lens Reflex) is a digital camera body that allows light to enter through a single lens, where it hits a mirror which reflects the light either vertical or horizontal into the camera’s viewfinder.

When you press the shutter to take a photo, the mirror tilts upwards, blocking the path vertically letting the light in directly. Then the shutter opens and the light from the lens reaches the image sensor.

The shutter stays open for as long as the image sensor needs to record the image. Then the shutter closes and the reflux-mirror returns to its original position and the light continues to return to(reach) the viewfinder.

Basic Parts of DSLR Camera

Lens: One of the most crucial pieces of the camera is the lens. As soon as light enters the lens, photo processing begins. The lenses might be mounted to the camera body permanently or be interchangeable. The focal length, aperture, and other parameters can all affect the lens.

Basic parts of dslr camera and their functions

Reflex Mirror: A reflex mirror is used to reflect a portion of the light passing through a single lens through the viewfinder. The same image captured on the camera sensor can also be seen in the viewfinder.

Shutter: Every camera has a shutter release button. This is the button on the camera that is used to open and close the shutter, enter the required light and information into the camera, and capture the image. The amount of shutter opening time depends on setting the shutter speed.

Aperture: The aperture is the opening inside the lens that controls what light is emitted on the image sensor .The aperture size indicates two things: first the depth of field, and secondly the shutter speed.

Image Sensor :Image sensors convert the optical image into an electronic signal and transmit it to a memory card. Two types of image sensors are commonly used in digital cameras (CMOS and CCD). The two sensors perform the same function but each has different performance modes.

Focusing Screen: The image seen in the frame is formed on the plastic screen inside the camera. The focusing screen is seen below the pentaprism of the single lens reflex cameras.

Penta Prism: Pentaprism directs light into the optical viewfinder. When the shutter-release button is pressed down, the mirror rises and the shutter curtain opens. This allows light to pass through the lens and go directly to the image sensor.

Eyepiece or Viewfinder: The viewfinder is an eye piece of  camera with a camera close to your eye to allow you to see what is being photographed. There are two types of viewfinders. Optical and digital.

Modes of DSLR Camera

The DSLR is one of the most popular cameras for both beginners and experienced photographers. It has lots of shooting options and settings for you to choose from. If you’ve just bought a new DSLR camera and want to get started shooting high-quality, professional images, here’s a beginner’s guide to help you set up your camera for success.

Dslr Camera Modes

Auto mode: When using a DSLR, you must decide which shooting mode you would like to use. The camera features a mode dial complete with several different settings. Automatic exposure is camera selects the optimal shutter speed, aperture, ISO and flash settings for your shot. All you have to do is click the button and take photo.  When set to auto mode, the camera automatically sets the focus and white balance for you.

Program mode(P):. The shutter speed and aperture are selected and set by the camera in programe mode. The camera has been configured to use a certain combination of shutter speed and aperture for any given brightness of light.

Aperture priority (Av) mode: Aperture priority mode lets you choose the aperture while letting the camera decide the shutter speed. Aperture is measured in f-stops(focal length/diameter of the effective aperture of the lens), which increases the size of the aperture as the f-numbers decrease.

Shutter priority mode(S): Shutter priority (S on the mode dial), alternatively referred to as time value (abbreviated as Tv), is a camera setting that enables the user to choose a shutter speed while the camera adjusts the aperture to ensure proper exposure. Use a faster shutter speed to capture fast-moving subjects, such as sports or wildlife. If, on the other hand, you wish to capture more motion and blur, a slower shutter speed is recommended.

Manual mode(M): On a DSLR, manual mode lets you control every aspect of the picture. You choose the shutter speeds, the f-stops, and the exposures, so you’re going to need to know how to properly balance those elements to digitally alter your surroundings and capture an accurate picture.

Types of DSLR image sensors

Different DSLR cameras use different sized sensors, but they’re capable of taking  camera photos to the next level. Full frame and APS-C are the two most common camera sensor sizes. Full frame cameras use sensors the same size as 35mm film format. The APS-C sensors are slightly smaller than the full frame sensors, which results in a reduction of the cropping factor. This small view field might be compensated with special lens attachments, but this is definitely worth considering when researching your compatible APS-C or full frame DSLR.

Camera sensors can be divided into

  1. CMOS Sensor(complementary metal oxide semiconductor)
  2. CCD Sensor(charge coupled device)

DSLR Camera can be divided on the basis of size or format.

  1. Full Frame (35 mm film format)
  2. Crop Sensor/ Half Frame (APS-C)

What Are the Benefits of Using a DSLR Camera?

Even though technology has progressed even further than DSLRs, Professional photographers have still many advantages to using this particular camera instead of others in digital photography.

Quick autofocus: DSLRs have advanced autofocus capabilities, which allow them to focus quickly. It’s important for sports and events, too.

Interchangeable lenses: DSLR cameras are a huge advantage for photographers. Being able to change your lenses gives you endless possibilities for different looks. The lens is arguably the most important aspect of photography. The camera lens determines most aspects related to the quality and ease of taking pictures. Therefore, you should focus on it. The lens has a big influence on the final product.

Optical viewfinder: With an optical viewfinder, you can see exactly where you’re pointing the camera, rather than relying on an LCD screen.

Long battery life: Optics require less power than other types of cameras.  Batteries last longer, so  spend more time taking pictures.

More storage: A digital camera stores images on its internal memory, and that memory can hold many more images than a memory card can hold. Don’t worry about wasting your expensive camera while trying to get your best shot.

Larger sensors: Megapixels don’t necessarily mean better picture quality. It’s not the number of pixels but rather the larger sensors in the camera that improve the quality of your photos. The larger sensor, the more light it captures.

Many add on: DSLR cameras are versatile in their ability to use add-ons, like mounts, flashes and triggers, so they offer a really customizable experience, giving you a wide range of options for taking your pictures.

What Are the Disadvantages of DSLR Cameras?

First, they’re big and heavy, especially professional DSLR camera. The rotating mirrors, auto-focusing sensor, complex viewfinders, and other features take a lot of space.

The optical viewfinder has its own set of problems. It has very few settings. For example, you can’t see the exposure yet. You can’t tell whether your shot will be correctly focused just by looking through the optical viewfinder.

The separate autofocusing sensor can cause headaches. If the sensor and the image sensor aren’t aligned properly, autofocus won’t work accurately. It may be difficult to keep your camera focused while taking a portrait.

Most DSLRs use a mechanical shutter, allowing them to be rated for certain exposure times before they fall permanently.

Why Do You Need a DSLR?

The question I hear most often about digital single-lens reflex (DSLR) cameras is why you’d want one over something else. There are many reasons to choose a DSLR over a smartphone or another type of camera. Here are just a few:

First, a DSLR offers a direct, optical view through the lens. This makes it easier to see what you’re shooting, especially when you’re trying to compose a picture.

Second, DSLRs allow you to take pictures in lower light conditions without having to use flash. Because there’s no electronic delay between pressing the shutter button and capturing the image, you don’t have to wait for the sensor to read the light in order to capture the photo.

Third, DSLRs offer better quality images because they use larger sensors than smartphones do. They can collect more light, allowing for brighter photos even in dim environments.

Fourth, DSLRs come with interchangeable lenses, giving you much greater flexibility than you’ll find with a smartphone or compact camera. With interchangeable lenses, you can change out different focal lengths and zoom ranges depending on where you plan to shoot. For example, you could go from wide angle shots to telephoto.

Fifth, DSLRs are built like tanks. They’re durable, reliable, and easy to operate. And, unlike some other types of cameras, they won’t break down unexpectedly when dropped.

Sixth, DSLRs are versatile. They work great both indoors and outdoors, making them ideal for different types of photography.

How to choose the best DSLR for you?

The entry-level DSLR market has exploded over recent years, offering consumers a wide range of options at different price points. This guide aims to help you pick the perfect option for you.

Beginners are advised to look at the following factors when deciding which model to buy:

DSLR camera can be divided based on 

Sensor size – DSLRs can be different types based on sensor sizes like full frame sensors and smaller APS-C sensors Both sensors make a big difference in the quality of the images. However, some cheaper models come equipped with APS-C sensor which is smaller than the size of full-frame camera.

Price – Based on your budget, you can divide cameras into entry level, mid level and professional. Entry level cameras can cost less than 50,000/- and mid level cameras can cost between 50,000 and 100,000. Professional cameras will become the above one and half lakh Indian Rupees. 

Company – Prices and size can vary from company to company. As per the companies, the price of DSLR and half frame sensors vary. There is no best or worst camera. A camera is just a tool. It’s important who’s behind the camera.

Conclusion

Film-based cameras were once popular for taking photographs, but with the passage of time, technological changes have taken place in the field of photography. With the advent of DSLR cameras, film-based cameras became obsolete and the photographic field was captured by DSLR cameras. With the advent of DSLR cameras came new changes in photographic image quality. But technological innovations have also brought changes to DSLR cameras. Today, the advent of mirrorless cameras in compact size over DSLR cameras has brought about great changes in video recording and photographic image quality. Perhaps in the future mirrorless cameras will have a place in the field of photography and cinematography.

Why are DSLR cameras better?

DSLRs offer higher quality images compared to point & shoot cameras. The main advantage of DSLRs is that they allow photographers to control all aspects of image capture from shutter speed to ISO sensitivity. This allows for greater creative freedom when capturing photos.

Which is better for beginners DSLR or mirrorless?

Both cameras are great choices for beginners, but I would recommend getting a DSLR camera first. The biggest advantage of a DSLR camera is that they offer much higher image quality than mirrorless cameras. However, mirrorless cameras are smaller and lighter than DSLRs, which makes them easier to carry around. If you plan to use your camera frequently, then a mirrorless camera may be a better choice.

What is the main purpose of a DSLR camera?

The main purpose of a DSLRs is to capture high quality photos and video. A DSLR has interchangeable lenses which allow users to change the focal length of the lens depending on what they want to shoot. This allows for creative shots such as close ups, wide angles, and long shots.
