Emissivity is widely considered to be the single most crucial parameter in thermographic praxis.

Emissivity may be interpreted as a radiative (not a reflective, nor an absorptiveā€¦) property of a surface. Emissivity is the ratio of radiation from a surface compared to the radiation of a blackbody at the same temperature.

In spite of being abstracted to a single fractional number, emissivity is tremendously complex and variable across temperatures, illuminance and irradiance, wavelengths, intensities, and directions.
