Understanding Light Measurement
Light measurement involves several different photometric and radiometric quantities, each with its own units:
- Luminance: Measures the luminous intensity per unit area of light traveling in a given direction
- Luminous Intensity: Measures the wavelength-weighted power emitted by a light source in a particular direction
- Illumination (Illuminance): Measures the total luminous flux incident on a surface, per unit area
Digital Imaging and Light Physics
Our converters also cover important aspects of digital imaging and the physics of light:
- Digital Image Resolution: Converts between different units used to measure the detail in digital images
- Frequency-Wavelength: Converts between frequency and wavelength for electromagnetic radiation, including visible light
Applications of Light Measurement
Accurate light measurement and conversion between units is essential in many fields:
- Photography and cinematography
- Architectural and interior lighting design
