Exposure Triangle

The exposure can be seeing either on information or when looking through the view finder:

             +2 means the image will be over exposed (too bright)

             - 2 means the image will be under exposed (too dark)

Seen like this through view finder : 

When taking an image, you must understand that there is a specific objective;

- pictures of sports

- a family portrait

- a landscape image

- capturing a band in a dark venue

Depending on the objective, this will influence your choice of ensuring aperture of shutter take priority. Only use ISO when you are struggling to get enough light into the camera.

Setting up exposure:

Set the camera into manual mode, the wheel at the top right controls the shutter speed

ISO button works independently (click the ISO button and will come up on the screen)

In manual mode, hold the av button and rotate wheel to change the aperture value.

The best way of dealing with the task is to think about the required or necessary setting to capture the best image in the scenario given.

e.g - if i wanted to capture an image of someone walking past me, i would prioritise the shutter speed over anything else as it is involving movement
