Sydney Opera House – Reflection of light.
The light reflecting off the tiles has actually been first reflected from the sky and clouds, with the size and shape of the reflection being proportional to the clouds above. This demonstrates specular reflection produced by the glossy tiles and it can even be seen on the other roof section farthest away. The tiles also exhibit diffuse reflection, where uneven grooves across it send the light waves in different directions due to the incidence/reflection relationship, giving a the image a distorted appearance.
The degrees of reflectivity are noticeable with the effects produced from the contrasting tiles. The non-reflective tiles present a greatly more diffuse surface, where the reflection gives a much more uniform colour across the tile and the light seemingly spreads evenly, not producing an actual clear image. The resonant colour of a greyish blue is a resulting mixture between the blue light from the sky, the colour of the tiles themselves and the angle that the shot is taken at. When looking across a reflective surface, there comes a point when the angle is acute enough so that the reflecting image is seen more than the surface itself. An example of this may be when looking directly perpendicular to a clear piece of glass and seeing through it, then tilting the glass to an acute angle and seeing a resounding reflection off it from the surroundings rather than actually seeing through the glass.
