Focal Lengths: The angle of view

For the first part of this project we are looking at how changing lenses affects the angle of view.
This exercise requires a view that is open with some details in the distance, then a series of photographs taken from a fixed point, with each shot increasing in focal length from wide to telephoto.

18mm

50mm

70mm
These photos show that as focal length is increased, angle of view decreases or 'closes in' and the subject or scene appear's to move closer. This is different to actually moving closer to the subject as that would affect perspective. The relationship between the subject and objects within the scene stay the same although they appear larger/smaller
