This paper presents measuring system LDA (Luminance Distribution Analyzer) which is dedicated for evaluation of illumination and light sources using digital photography. Thanks to the precise calibration of camera we achieved the precision adequate to the standard measuring instruments. Calibration includes spectral characteristics of the sensor, geometric properties of the lens, and the mechanical behaviour of the camera itself. However, the indisputable advantage is the speed and efficiency of the measurement and the following analysis of the data. For example, instead of a large number of individual measurements using the luminance meter just take one picture of a room, subsequently illumination at the arbitrary point can be easily subtracted. The paper describes the abilities of developed software and shows several examples of its real application.
