Focal lengths and different viewpoints

This exercise demonstrates how perspective as well as angle of view changes when the viewpoint is altered as the lens is changed.
Two pictures of a scene were taken, the first with the lens set to telephoto with the subject filling the frame, the second with the lens set to wide angle and moved closer to the subject so that again the subject looks the same size as the telephoto shot through the viewfinder.
 In the first series that I have displayed here I used the monument as the subject, I know it did not fill the frame however I thought that the relationship with the building behind would demonstrate perspective.

This exercise demonstrates how perspective changes with different focal lengths and viewpoints.
The longer focal lengths create a 'compressed', 'flatter' perspective, the background moves towards the subject and the scene loses depth, subjects within the scene appear less separated than they actually are especially if they are already close.
The wider focal lengths creates depth within the scene, the subject appears deeper and more defined, relationship with other objects within the scene are more defined and separated, the back ground moves away and linear perspective is enhanced (even distorted).
Of the two extremes of perspective within this task I prefer the wide angle shots, however I can appreciate the merits of both and will certainly be considerate of wide angle v telephoto in the future.
