The total amount of energy that flows from the light source (units: watts);

The achromatic notion of image intensity.

represents the dominant colour and is mainly associated with the dominant wavelength in a range of light waves.

indicates the degree of white light mixed with a hue

is used to demonstrate the mixed colours where a straight line segment connecting two points in the chart defines different colour variations.

refers to a coordinate system where each colour stands for a point.

is the study of how colors work together and how they affect our emotions and perceptions.

In color theory, __________ are groups of colors that are next to each other on the color wheel.

are pairs of colors that are opposite each other on the color wheel and create high contrast when placed together

is mainly conducted based on the colour differentiation. It is a grouping process that enables image pixels to be separated according to their colour intensities

is the electromagnetic radiation of photons which are in a range visible to the human eye.

Is a way to describe the light appearance provided by a light bulb.

Reflected light is measured by the illumination of the object on a Lux scale, Lux being a measure of Lumens per square metre (Lumens/sq.m.).

is usually an optical quality glass disc that is ground into a convex shape with a refractive quality so it can bend a ray of light to a precise point without distortion.

has a physical length shorter than its focal length

This is the measure of the distance (usually in millimetres) between the optical centre of a lens and the focal plane.

_______means an opening, in this case one which allows rays of light through it to illuminate the focal plane

This is the proportional time the film or sensor is exposed to the light coming through the aperture.

is a post-production editing application that combines editing, color correction, visual effects, motion graphics, and audio post production into one software tool
