What is a DSLR camera?
The term "digital single-lens reflex camera" (also known as "digital SLR" or "DSLR") refers to a type of digital camera that combines a digital imaging sensor with the optics and mechanisms of a single-lens reflex camera.
In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the viewfinder, or the image sensor when the shutter release button is pressed.
Identifying the buttons
It is a small cogwheel located on the top-right of the camera that switches between the camera's modes. Eg Manual mode, automatic mode etc
Is a cogwheel on the front of the camera that allows you to change the aperture, shutter speed, exposure compensation, and other settings. Though not present in all cameras.
It is usually a large button along the top of the camera, near your right index finger when holding the camera. It is the button that you press to take a picture.
It is a flash unit built into the main camera body. They are typically unidirectional.
Flash Sync Contact
This is the contact where the flash is electrically connected to the camera
Power Switch turns the camera off and on
The ISO setting controls how sensitive your camera is to light.
This enables you to review images (and videos) on the LCD screen.
It allows you to access the extensive range of settings found on the majority of digital cameras.
Is used to frame your shot, view menus and camera settings, and replay captured photos and videos (when using Live View).
It can be used to display camera settings on the rear monitor, access additional information, and on some cameras, guide modes.
This button is typically denoted by a trashcan icon. It can be used to delete one or more photos.
This button usually has a "+" and a "-" on it. You can use it to manually set the exposure for the photo
Cross Keys Button

Is a ridge on the right side of the camera that makes holding the camera more comfortable.
Advantages of a DSLR Camera
DSLR cameras produce great image quality, thanks to high megapixel counts and large sensors.
Flexibility and customization
DSLRs are very flexible cameras with tons of customisable buttons to control each aspect of the camera
Instead of relying on a digital LCD monitor, the optical viewfinder allows you to see directly through the lens as you frame your shot.
With DSLRs, you have unlimited possibilities by being able to change lenses.
Good low-light capability
DSLR cameras handle low light very well. This is as a result of the high megapixel counts, larger sensors and the ability to change into a lens with a large aperture are responsible for this.
Long battery life
The batteries of DSLRs generally last longer than that of other cameras.
DSLRs are typically built to withstand terrible weather, rough terrains and handling and other elements.
Due to the size of DSLRs, photographers with larger hands will have a good experience handling DSLRs
Disdvantages of a DSLR Camera
DSLRs are typically bigger, heavier and bulkier when compared to other cameras. As a result, they are not the lightest or the most convenient things to carry around. And after extensive use, the back and necks definitely suffer from such cameras.
Thanks to higher quality sensors , higher megapixels, other inner components and features, DSLRs tend to be quite expensive. Also, after purchasing a DSLR body, you will need to invest more money in additional accessories like lenses, speedlights and additional camera components.
A beginner would need some training to get familiar with all the buttons and features of DSLRs.
