Exploring the intricacies of how light interacts with different surfaces will deepen our understanding of how to capture the world’s beauty through the lens, unveiling the secrets of color and illumination in the captivating art of photography.
How Objects Absorb or Reflect Light
The world of colors around us is a fascinating interplay between objects and visible light. The colors we perceive in everyday objects are not inherent properties of those objects but rather a consequence of how they interact with the visible light spectrum.
When we see a red dress, for example, it appears red because a selectively red dress reflects red light while absorbing all other colors on the visible spectrum, especially when it receives direct sunlight. This means that the dress absorbs colors like blue, green, and yellow, but it reflects back the color our eyes interpret as ‘red’. In essence, the color we see is the light that the object does not absorb, allowing us to experience the world in a vibrant array of hues.
This concept of how is visible light used in photography is at the heart of how photographers capture and portray the world through their lenses. Understanding the interaction between objects and light enables them to play with colors, lighting conditions, and shadows to create striking and evocative images.

The Blue Sky Phenomenon
You may have wondered why a clear daytime sky appears blue instead of any other color.
Short-wave light, like violet or blue light, being spread out in the sky more than longer waves, such as yellow and red light, causes a phenomenon known as Rayleigh scattering.
Science Daily’s article on Rayleigh Scattering explains this concept in depth.
However, despite being at the high-energy violet end of the spectrum, our skies appear blue instead.
This can be attributed to two main reasons: firstly human eye is less sensitive towards violet compared to blues; secondly, sunlight reaches us indirectly after getting refracted through Earth’s atmosphere, where shorter wavelength lights get absorbed by the ozone layer.
Therefore while both these factors contribute together, making our skies look predominantly blue during clear weather conditions.
Impact of Lighting Conditions on Photography
The lighting conditions under which a photograph is taken can significantly alter the image’s overall mood and color balance.
