This Spotlight discusses how to use a standard commercial digital camera as a very exact metering device in correlation, colorimetric, and intensity measurements. After extracting and calibrating linear data from the camera matrix, the resulting characteristics are comparable with those of technical cameras.
Progress in computer processor speeds and in calculation techniques led to a jump forward in the use of digital image processing such that it is now widely used in all fields
of research, practically displacing pure optical analog methods. This Spotlight considers three fields in which measurements could be implemented with the use of an ordinary digital camera: distance, intensity, and wavelength.
