Brightness, represented by the symbol br, is a measure of the amount of light that is emitted or reflected from a surface. It is often quantified in terms of illuminance, which refers to the amount of luminous flux per unit area. This measurement is crucial in various fields, including photography, architecture, and lighting design, as it helps determine how well-lit a space is.
Brightness is standardized using units such as lux (lx) and foot-candle (fc). One lux is defined as one lumen per square meter, while one foot-candle is equivalent to one lumen per square foot. Understanding these units is essential for accurately measuring and converting brightness levels in different environments.
The concept of brightness has evolved significantly over time. Early measurements were based on subjective assessments of light intensity. However, with advancements in technology and the development of photometric standards, brightness is now measured using precise instruments. The introduction of digital light meters has further enhanced our ability to quantify brightness accurately.
To illustrate how to convert brightness levels, consider a scenario where you have a light source emitting 1000 lumens over an area of 10 square meters. The illuminance can be calculated as follows:
[ \text{Illuminance (lux)} = \frac{\text{Luminous Flux (lumens)}}{\text{Area (m²)}} ]
[ \text{Illuminance} = \frac{1000 \text{ lumens}}{10 \text{ m²}} = 100 \text{ lux} ]

The candela (symbol: cd) is the SI unit of luminous intensity, representing the amount of light emitted by a source in a particular direction. It is a fundamental unit in photometry, which is the science of measuring visible light as perceived by the human eye. The candela is crucial for understanding how light interacts with our environment, making it essential for various applications in lighting design, photography, and visual arts.
The candela is standardized based on the light emitted by a source that radiates monochromatic light at a frequency of 540 terahertz (THz) and has a radiant intensity of 1/683 watt per steradian. This standardization ensures consistency in measurements across different contexts and applications, allowing professionals to rely on accurate and comparable data.
The concept of the candela has evolved significantly since its inception. Initially, it was based on the light produced by a specific type of candle. However, as science progressed, the need for a more precise and universally applicable unit became evident. The candela was officially adopted as part of the International System of Units (SI) in 1979, reflecting advancements in photometric measurements and technology.
To illustrate the use of the candela, consider a light source that emits a luminous intensity of 100 candelas. If you want to calculate the total luminous flux (in lumens) emitted by this source over a solid angle of 1 steradian, you would use the formula: [ \text{Luminous Flux (lm)} = \text{Intensity (cd)} \times \text{Solid Angle (sr)} ] Thus, for our example: [ \text{Luminous Flux} = 100 , \text{cd} \times 1 , \text{sr} = 100 , \text{lm} ]
