Photography, Light and Colour

The understanding of light and the effective use of colour in creative work and digital p photography. People effectively using colour in creative work and digital photography has been around for a long time now, and the study of light and colour even longer. In this essay I plan to effectively communicate how the human brain perceives light and how the understanding of this has culminated in creative work and photography. Although photography as an art form is relatively new compared to classical art there are a lot of interesting and relative comparisons between the two when it comes to colour science. After all photography is essentially painting with light.
Scientists and artists who have studied light and colour have changed and contributed to the world that we live in today. For instance the words you are reading off this page right now are just a mix of Red, Green and Blue light in the pixels on your computer screen. Without breakthroughs in colour science and understanding in human colour vision this would not be possible. The understanding of light and colour science has made it possible for artists and creative workers to effectively use colour in their works and kaleidoscopic beauty into the world. After all, without light there is no colour and without colour the world would be a terrible dull place. And where is the fun in that?
Figure 1. Light Diffraction If we do not understand the science of how the human body perceives colour then we cannot fully utilise the colour spectrum. Be it for art, design or photography. Therefore it is important to know how the colour vision system works. Essentially without light there would be no colours in the world. The process of giving colour to this world happens within our brains and vision system.
