Choose a subject in front of a background with depth. Select your shortest focal
length and take a close low viewpoint, below your subject. Find a natural point of
focus and take the shot.
You’ll see that a very wide lens together with a close viewpoint creates extreme
perspective distortion. Gently receding lines become extreme diagonals and rounded
forms bulge towards the camera. Space appears to expand. The low viewpoint adds
a sense of monumentality, making the subject seem larger than it is, and tilting
the camera adds to the effect as vertical lines dramatically converge. Not the ideal
combination for a portrait shot!
The shots below were taken with my Fuji X30 at its shortest focal length of 28mm. This is wide but not extremely, so the shots while not ideal show some distortion. Unfortunately there were not any high buildings or objects so there is not much in the high background to demonstrate the distortion effect. But the low-lying object do show distortion and parallel lines demonstrate convergence. This does give an impression of grandeur and largesse. But not (as mentioned in the brief) very flatering for portraiture. Though this effect could be used to great effect to make someone look powerful or important if used with care, judgement and good lighting.
