WHAT IS A DSLR CAMERA?

First of all the acronym DSLR means Digital Single-lens Reflex.

A DSLR camera simply refers to a portable camera with an internal mirror and present system that is used to direct light from the lens to the viewfinder of the camera composing an image.

You might be wondering whatever you find out is. The viewfinder is a part located at the top of the camera which shows the location of where the subject is people often look through the viewfinder to see whatever they are capturing.

HOW IMAGES ARE CREATED IN DIGITAL SINGLE-LENS REFLEX  (DSLR) CAMERA

The method through which images are being formed in all digital cameras are the same. It is the light that makes the camera lens to see, so first of all the lights that bounces on the subject or object is being collected and focused into the camera lens to the camera sensor which saves that light information in an image file that you can view on edit. The sensor is responsible for creating the main image based on the reflection of light that is been collected through the camera lens.

The difference between a digital single-lens reflex (DSLR) camera and other cameras in the market is that the DSLR camera has a mirror prism system which is used to send light to the viewfinder for the area of the subject or object to be seen.

To confirm this if you take the lens off a DSLR camera and look inside the lens Mount you will see the mirror prism inside, it is just reflecting the light up towards the optical viewfinder. Remember to see this you must remove your DSLR camera lens first.

When you press the shutter button of the digital single-lens reflex (DSLR) camera, the mirror prism inside flips up and allows light to pass to the sensor creating an image or a picture. 

DIGITAL SINGLE-LENS REFLEX (DSLR) CAMERA CONTROL

Although there are different types of DSLR cameras out and each of them are having their settings or mode of operations but the basic things to know is that they have different control buttons.

When you first take your new digital single-lens reflex camera out of its box you’re going to see that it has a lot of buttons and dials on its body and this can certainly be overwhelming, which is likely why so many people that are learning photography mostly use the automatic control button in order to get everything automatically done for them by the camera.

  • It takes time to understand all the control buttons in a camera but it’s really worth it because it will give you full experience on how to manipulate and how to capture your pictures one way or the other.

Here is an overview of the key controls on a DSLR camera or do it depends on the camera model this likely have different but most of the cameras have the following controls;

MODE DIAL

 the mode dial is located at the top of the camera and is the first dial you will want to locate and use in the camera. The mode dial carries different mode of actions the camera performs, it depends on what you want the camera to do. You can change the camera mode settings on the mode dial by rotating it was the direction of any mode of function which includes;

  • Auto Mode (A); this refers to automatic mode which controls the camera by automatically doing the right settings for the operator
  • Manual Mode (M); this mode allows the operator to manually set the camera to his or her own taste it deals with manipulating settings to get the best result
  • Program Mode (P); this is another automatic mode which mostly have controls control over some settings including
    •  Exposure compensation setting 
    • ISO setting
    • White balance setting
  • Aparture Priority Mode (A or Av); this is the camera mode that allows you to only set the aperture and the camera will automatically and the other settings to match with the aperture setting for best results. The setting is good in terms of getting depth in pictures.
  • Shutter Speed Mode (“S”  “T” or “TV”); the shutter speed mode is also known as shutter priority it is just like the aperture setting. Beast mode gives you room to only set the shutter speed and the camera will handle the rest of the settings in order to match the shutter priority for best picture results. This setting is mostly used for action pictures like sports, weddings and riot.

DIGITAL SINGLE-LENS REFLEX (DSLR) CAMERA EXPOSURE

When it comes to the exposure setting of every DSLR camera there are three basic things to to manipulate or control because they are the only setting that will handle the over exposure or under exposure of a picture. These three things are;

  • ISO 
  • Aparture
  • Shutter Speed

ISO (INTERNATIONAL STANDARD ORGANISATION)

The issue is one of the most important control over the exposure of an image. Increasing the ISO makes the camera sensor more sensitive to light and reducing it reproduces the sensitivity to the light. ISO button is located on the body of the camera. 

  • The  exposure level is from 100, 200, 400 and above depending on the type of camera.

APERTURE

The aperture is an opening in the camera lens that allows light to pass through straight to the sensor. Setting this aperture properly also contributes to the exposure of an image. It is said that the wider the aperture the brighter the picture and the smaller the aperture the darker the picture.

SHUTTER SPEED

This refers to the speed at which the camera captures an image. There’s a setting for this speed. the faster the shutter speed the good image you will have, the slower the shutter speed the blur and unclean image you will have, so setting shutter speed also plays a vital role in getting a good exposure of an image.
