Aim: The aim of this exercise is to understand and appreciate the effect of changing focal length.
Plan: I planned to spend the day in Manchester for a series of exercises. There are a number of large squares that I could use for this exercise that would give me a clear view across from one side to the other.
The following shots were taken in succession across the square from a wide angle covering the whole of the square to a a tighter zoomed view covering the statue on the with a far side. The camera was mounted on a tripod.
|F16, 1/13 sec, 18mm|
|F16, 1/13 sec, 30mm|
|F16, 1/13 sec, 75mm|
|F/9, 1/20 sec, 250mm|
Changing focal lengths over even a small amount can have a great effect on the focus of the image.
Different objects in the frame became focal points with changing importance as I zoomed through the lens range.
