Lighting

Just finished reading a book on lighting called’ Master Lighting Guide’ by Christopher Grey and found few useful notes:

The way light bounces off a subject and creates colour that we see with our eyes is called the Angle of Incidence.  The angle of incidence (the angle that light strikes the surface of an object) is always equal to the angle of reflection (the angle at which that same light will be reflected off the surface).

See photo below:

The quality of light is a determining factor in the appearance of the subject’s form – a small light source with a concentrated beam will produce deep sharp shadows on the subject, a larger source will throw a wider beam of light with shadows that are more open and less dark because more light spills into them.  As the light source is moved away from the subject it becomes smaller in relation to the subject and will create sharper shadows.

Key Light – the light that is aimed at the subject and which the primary light meter reading is based on is called the key light as it is the key to the entire lighting scenario.
