Looking at Light

The concepts of looking, seeing and observing are very different. The definitions of looking is readying yourself to see something, seeing is when the eye actually receives light energy and converts it into impulses and observing is when we analyse, interpret and decide what the nerve impulses are i.e. object or an effect.

On cloudy days light appears white however it has a bluish tint. The clouds actually act in such a way that they soften the light and diffuse it, spreading it out.

Front lighting occurs when the light source is behind the person observing the object which evenly lights the object. Side lighting creates strong shadows which emphasizes texture and adds depth to an image. The most dramatic lighting though is back lighting meaning the light source is behind the object creating silhouettes and other interesting effects.
