Introduction to DSLR (Digital Single Lens Reflex)


A DSLR camera basically means a camera with one lens and a mirror which reflects the light, where  pictures are recorded on a digital card instead of a film.

In this blog, I will be showing the key features of a DSLR camera. I will be using a DSLR camera to film my preliminary task.



Start with auto settings:

  • Set the dial to the green automatic mode.
  • Make sure the lens is set to AF (auto focus) and not MF (manual focus).
  • Push shutter button halfway - camera will focus on the subject.
  • Push the rest of the way down to take the picture.
CAMERA SETTINGS - Aperture, Shutter Speed and ISO settings directly affect exposure but more importantly they allow you to control how each photo will look.

Exposure:

  • Amount of light a digital camera sensor captures when a photo is taken.
  • To much light results in a washed out photo (overexposed)
  • To little light and the photo will be to dark (underexposed)
  • Exposure is affected by aperture, shutter speed and ISO.

Aperture - setting controls the size of the lens opening that allows light to your camera.

  • You can blur the foreground and background that brackets your subject (known as shallow depth field) by opening the aperture with a low F - stop number. 
  • you can keep your phone sharp from the foreground through to the background (known as wide depth field) by closing up the aperture down with a high F- stop number.

Shutter Speed-controls how long the shutter opens to expose the image sensor to that light.

  • You can show the movement of a fast moving subject by keeping it open longer with a slow shutter speed.

ISO- How sensitive image sensor is too light.

  • The higher the ISO the lighter and brighter the image
  • The lower the ISO the darker and less light there is 
  • ISO will cause graininess so as a rule use lowest ISO as possible.

Shooting in low light = boost your ISO
Shooting in bright light = lower your ISO
