Focal lengths - different viewpoints

Exercise: Focal lengths and different viewpoints (2 or more photographs)

This exercise was to show how different focal lengths and a change of viewpoint can have on the perspective of a photograph.

I photographed a covered gateway to a local church to demonstrate the difference in prospective.



Image 1 - 190mm @ f10


Image 2 - 29mm @ f10

Image 1 as stated was taken at 190mm and gives an impression that the entrance door to the church in the background is a lot closer to the gate. The telephoto lens reduces the impression of depth by compressing the planes of the image. It leaves the parallel lines and right angles as they are, this gives the viewer a less involved view of the gateway, distancing them from the it, giving them a more objective way of viewing it. 

In image 2, taken at 29mm the entrance door to the church appears to be a lot further away, this is due to the wide angle lens as they change the apparent perspective and so the perception of depth. The tiled roof the entrance gates is emphasised, this again is due to the wide angle lens as they have a tendency to produce diagonals creating dynamic tension drawing the viewer into the scene, it occupies the upper part of the photograph and giving it a very strong presence.
