Exercise: Focal Length and Angle of View

In this exercise I've had to take 3 photographs, one standard view (as our eyes see), one wide angle and one zoomed. After printing these on A4 the exercise was to take them back and check and measure the distance at which these image become true to life.

I decided to carry out my first exercise on Harting Down while out on a walk one day.

Final thoughts ... I was surprised that even though my camera 'Canon 550D' which has a 1.6x crop factor that the standard view was recorded at 55mm focal length. I would have thought it would have been less.
