Photography 1.1

OUR FIRST LECTURE!!! Damn, it is good to be back. I am so tired of constantly working all the time during summer! I need to start doing something creative. So, in our first lecture we were learning on how camera is functioned, on technical side, and practical side.

  • Red line = light.
  • Light travels through the lens, between the aperture blades. The first mirror catches the light and bounces it to the second mirror on top, which reflects it on to the view finder.
  • The shutter and the sensor are not exposed to any light at this stage.

Aperture will control the image sensor’s degree to exposure of light.

  • This is what happening when you click the shutter button.
  • The first mirror and they shutter snap out of the way, to let the light through.
  • The sensor captures the light and records the picture.
  • Which is then saved onto a memory card.
  • You will not be able to see anything through the view finder.

There is some helpful YouTube videos:


These are the things we need to concerned about before using a camera:

  1. Battery life is enough for you to use.
  2. Camera isn’t damaged.
  3. Enough storage on the memory card.
  4. Reset the settings.
  5. Set up the date correctly, when you’re taking multiple series of pictures.


Later on, we learn on how to use the camera, its settings and all the useful tips. But, we were especially focusing on the exposure compensation on how to quickly adjust the brightness. And AF point button to allow us to know what the camera is focusing on.

Other things that we learnt:

  • ISO (International Standard Organisation) is the sensitivity of the sensor.
    • 100 ISO is suitable for a sunny day and shooting outside.
    • 800/1600 ISO is better for indoor.
  • DLSR camera gives much more control than your phone camera. Therefore, it allows us to communicate our ideas more effectively.
  • Exposure is measured in stops.
  • ISO always go up in double.
  • Stopping down reduces the exposure.
