1. Light and colour can influence how people perceive the area around them. Different light sources affect how the colours of walls and other objects are seen.
Only light colored, light generated in the light source. Light emitted by different light sources, the color feel different. In the same object will show different light sources of different colors: white under white light illumination is white, the red light in the white into red, green illumination in white and green. In addition, the intensity and angle of light also affects the color of an object, the object color will fade under bright light, low light-colored objects will become blurred dull, only moderate light intensity in the most visible object color.
In this experiment, I photographed the changes of colour on the wall in different situations; I have chosen to use two different sources of light: home lamp and natural sun light. The colour of wall involved in this experiment is white colour; the colour of wall changes under different light sources below.
Figure 1
Figure 1 is a photograph taken using home lamp, and the colour of wall appears to be orange and yellowish.
Figure 2
Figure 3 is a photograph taken using natural sunlight, the colour of the wall stays its own colour white.
2. Specific hues of colours seen under natural light may vary when seen under the light from an incandescent (tungsten) light bulb: lighter colours may appear to be more orange or "brownish" and darker colours may appear even darker.
To prove this theory, I also provide photographic evidence for this assertion experiment. In this experiment, I plan black and white two objects by using different light shooting, making the contrast. One is the use of home lamp and one is the use of natural sun light.
Figure 3
Figure 3 is a photograph taken using home lamp, the black part to be dark, white part becomes orange.
Figure 4
Figure 4 is a photograph taken using natural sun light.
3. Light and the colour of an object can affect how one perceives its positioning. If light or shadow, or the colour of the object, masks an object's true contour (outline of a figure) it can appear to be shaped differently from reality.
To help to prove this theory, I photographed using 2 different light condition.
Figure 5
Figure 8 is the use of household lights at night in a low light conditions; in this picture, one is very vague.
Figure 6
Figure 9 is taken in enough light is provided to this photo flash state, the object is very clear.
4. Objects under a uniform light source will promote better impression of three-dimensional shape.
Figure 7
Figure 8
When covering the entire perimeter of the light object, subtraction, figure 7 when the light cover to the right of the object, then the shadow of the object will appear in the left. However, figure 8 when the light of an object all over, there will be no shadow from the object. I intend to take photos of boxes of different light sources: the light evenly and so on.
5. The colour of an object may affect whether or not it seems to be in motion.
