- Lux (The Measuring Unit): Unit of measurement for light in photography. Lux is the SI unit that is used to measure the amount of light in photography. It basically measures luminous flux per unit area and the luminous flux is nothing but perceived power of light. Therefore, higher the luminous flux more will be the power of the light. The following table gives us a good insight into the SI …
Lux - Wikipedia
- https://en.wikipedia.org/wiki/Lux
- The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted ...

- In SI-derived units, illuminance is measured in lux (lx) or lumens per square meter (1 lx = 1 lm/m² = 1 cd·sr·m⁻²). In the CGS system, the unit of illuminance is the phot, which is equal to 10,000 lux. In photography a non-metric unit of illuminance, the foot-candle is often used. Foot-candle is defined as the amount of illumination the inside surface of a 1-foot radius sphere would be …
