Pt 1, Ex 5 Focal lengths and different viewpoints

The subject of this exercise was Temple Bar in London which acts as a gateway between St' Paul's Churchyard and Paternoster Square (more info here).
Two shots were taken and the originals can be seen in this Flickr set


Temple Bar 1.jpg ISO400, 32mm, 1/80, f/14
The first image is a pretty standard shot.  It's square on and is fairly ordinary.  It defines the the subject in context with it's immediate surroundings.  At 32mm focal length it's fairly wide and this can be seen by the straight edges bowing slightly

The second image was taken at 10mm and with such a wide angle I felt like I was almost standing underneath the subject. The height and depth have all become exaggerated and the entire structure appears to be leaning backwards.  The image is not easy on the eye and the distortions dominate.

Using wide angles can bring some interesting and pleasing results, but the subject matter has to be taken into consideration.  Wide angles can emphasise subjects, such as in the following image of one of my sons throwing a stone into water.  The close proximity of the camera and the wide lens exagerate the pose and infer the essence of movement, even though a fast shutter speed was used.

Similarly, telephoto lenses 'flatten' images, resulting in a reduction in depth in the photo, with large distances compressed.  The subject of the photo below was about 4 miles away from where it was taken, but the large telephoto lens make it appear much closer
