Exercise 2.1
“Find a scene that has depth. From a fixed position, take a sequence of five or six shots at different focal lengths without changing your viewpoint. (You might like to use the specific focal lengths indicated on the lens barrel.)”
The following shots were taken to illustrate how changing focal length of a lenses changes the angle of view from a fixed position
All the Focal Lengths quoted are on a full frame body.
24mm
28mm
34mm
48mm
This shot is closest to the view scene as viewed by the human eye
70mm
The above exercise returned the results that I expected; there is no real change in how this look in the imag. As is suggested to create a vastly different look when changing focal length you would need to combine with a change of view point
