This exercise involves taking a series of photographs from a stationary position using different lenses to study the effect focal length can make to an image. The following images were taken on a very cold and blustery day at St Andrews beach. The lenses I used for this exercise were a Canon telephoto lens with a focal length between 70-250mm changing to a Sigma wide angle lens with a focal length between 10-20mm.
As the focal length of the lens gets shorter you can see the angle of view getting wider. This next image was taken at 55mm.
Then changing to the Sigma 10-20mm lens for a much wider view below. This image taken at 20mm.
I have moved to the right of frame slightly for this image as the waves were lapping at my feet - but even if I hadn't moved - if you compare this image to the first image at 214mm they could have been taken at totally different places. The change in lens to a wide angle lens has totally changed the feel and style of the image.
