Friday Tip: Changing the Perspective
We all know that a telephoto zoom lens will bring faraway objects closer but another benefit of a long lens is the ability to compress the perspective ie: make the objects in the foreground appear closer to the objects in the background.
The following two shots were taken on the Fujinon 55-200mm zoom lens, the top image was taken at 200mm and the bottom image at 55mm. The island is Bass Rock and the doorway is through the wall on the cliff top walk here in Dunbar.
By walking further away from the doorway I was able to frame Bass Rock to give me the following composition at a focal length of 200mm -
The second shot below was taken at a focal length of 55mm. By moving closer to the doorway I have been able to keep it at about the same size in the frame while making Bass Rock appear smaller.
This effect is also called stacking and by using longer focal lengths you can make the various elements in the image appear a lot closer (stacked) together, the longer the focal length of the lens the more stacked the elements appear.
A good example is this image of Lismore Lighthouse in the Sound of Mull. This was taken on a Sigma 50-500mm lens set to the 500mm end of the range on a Nikon D90.
The lighthouse is clearly visible in the foreground while the lighter elements in the background are the mountains of Mull, which are actually several miles behind the lighthouse but appear very close because of the change in perspective caused by the telephoto effect.
