The observation process started at 6.30 pm in the middle of Caufield Park, during that time sunshine still flashed across the sky, which landed on the grass, the tree, the bench, the building, and the rubbish bin and other moving objects such as people, dogs and birds.

Light is known as a very crucial component on our vision system eye requires a certain level of light intensity for the retina to process into image but It is also important for the iris to moderate the amount of light that enters the eye because too much light could cause the retina to struggle to process images *how light effect on your eye 2016, optrex. As it was still quite early, and the sun light was strong, it was quite hard to see things far away and also unable to detect a clear motion and movements of surroundings environment as the eyes had trouble to process the imagine. However, roughly 30 minutes later, the sun light is much more moderate, the sky is azure and things have become much more visible to me; the colours green of the leafs, the movement of the leafs as the wind passes by, the colour of the benches are brown with a touch of red and also the surface of the bench itself is very glossy. It is also become much more visible to visual system regarding to the movement and the physical aspects of people and animals in the park. With the acknowledgement motions, colours and the texture, the link to emotion

  I also observed the colour of the building, which is constructed in the middle of green grass field background, the building was painted in green (green mixes hint of black) on the top floor and also black with a hint of grey in the ground floor, the wood material which is used for the door can also be detected. Moreover, we also can see shadows of the buildings, benches, trees and etc as the those objects are opaque and they block light

One thing that is quite intriguing is that when the sun light changes its directions and only flashed to half of the grass field, the colour of the grass where the sun hit is tiny bit yellower and glossier and the other half without the sunlight, the grass is greener.




Moving to the second part; the changes of light during the sunset and its impact on how we see things will be discussed.

It is obvious that the colour of the sky is different as now as the sun going down, the light dims and the sky divided into 3 different colours which are cerulean blue, pink and yellow. It is surprised to me that even though I have seen the sunset countless of time but I have been unconscious about the changes in colours and texture of things as light change. It is observed that the colour of objects such as grass, leafs, trees, benches and building become much darker. For example, the bench which had a rich brown/ redish colour has changed to much darker brown, for the benches which were further away, the colour now looks much more like black. During this time, I am still able to see motions, clothing colours of people and also sizes and colour of animals around me but they were not as vivid and clear as before.  These changes may due the distributions contain different amount of wavelength; long wavelength (red), middle-wavelength (yellow), and short wavelengths (blue) at different point of time during the day.




As it becomes darker, it is hard for identify colours because our visual systems are not designed to see colours when there isn’t much light. When the sky become darker, the sun light has disappeared, it reaches the point where our cone can’t respond. As our visual system has a parallel system that help us to adapt to the changes of light in the world so we can see things. During the day, with a high level of light, our cones are in charge of seeing colours and details. However, the cones cannot be very sensitive to light. As the light levels decrease at night, we reach a point where our cones can no longer respond because there simply is not enough light for them to produce a response. This is when our rods step in. Unlike cones, rods are not sensitive to colours, thus our eyes only able to shades of grey or black, or I think we could say that we are “colour blind” in the places with very limited light. During this time, I still can see the trees but not its colours, I know it is going to be green, but I think that’s the perception that we always have that trees are green, sky is blue. The benches which are located quite close to where I was sitting, I still able to point at them but their colours are black and the bench which is far away, located under the tree, I’m no longer see it. In term of the building, as it is a big object, I’m still able to see it but I’m no longer able to tell the colour differences, I may able to point out the wooden door but then there is a very little different in term of colours between the top floor (painted in green) and ground floor (painted in dark grey). Interestingly, twenty minutes later, I’m not able to take notes anymore as it has become too dark for me to actually be able to take note efficiently. HEARING
