(iv)       over exposure occurs when too much light reaches the film/sensor.
(v)        under exposure occurs when insufficient light reaches the film/sensor.

(b)        (i)         is the way in which objects appear to the eye based on their spatial

(ii)       perspective refers to the sense of width, height and depth
which creates three dimensional illusion in a photograph.
(iii)      it creates the illusion of reality in a photograph.
(iv)      perspective relates to visual clues that create a feeling of the three

(iv)      source of light can be natural (e.g. moon and sun) or artificial (e.g. a lamp, flash/studio strobe etc.).
(v)       it is used in creating mood and other visual effects.

(f)        (i)         it is the space behind the main subject in a photograph.
(ii)        it can be blurry or highly detailed/sharp.
