Aerial perspective
Objects at differing distances in a landscape tend to appear progressively paler and less contrasty the further they are from the camera position . These changes in tone create aerial perspective .
You can emphasize aerial perspective by arranging your camera position so that a dark toned object is included in the fore- ground . But still take care that the tone values in the main subject are recorded accurately . Measure the exposure so that mid - distance grays reproduce correctly . The final print will then include the pale detail in the background . Remember that in distant landscapes background detail may record weaker than it appears to the eye , and almost be lost , unless you use an ultra- violet filter over the lens ( see p . 101 ) .
For interior shots it sometimes helps to use aerial perspective to make a room appear much bigger than it really is . You can simulate the outdoor effects of haze and ultra - violet light by choosing lighting that emphasizes darker , close - up objects and progressively softens the tone of objects the further they are from the camera .
Using aerial and linear perspective
In the picture , above , a strong feeling of three dimensions and depth has been achieved by both the viewpoint and lighting . The position of the window gives lighting quality and direction that creates a sense of aerial perspective in a relatively small space . The wheel- chair in the foreground appears almost as a heavy silhouette and objects generally become paler in tone the further they are from the camera . Also , by choosing a view- point in the corner of the room and using a wide - angle lens , a two point linear perspective has been formed . Lines converge strongly toward two vanishing points out- side the picture , left and right .
Aerial perspective in landscapes
The scene , left , is given consider- able depth by the way tones change with distance . The background mountains are very pale in tone , showing the effects of haze and light scatter by air molecules . The hills in the middle distance and foreground appear progressively- darker and stronger in tone . The aerial , or atmospheric , perspective effect here is greatly helped by the low lighting from the side and rear .
