Abstract

Scene illumination analysis and control systems and methods that can measure the intensity and wavelength dependent distribution of light illuminating a scene, determine any differences between desired illumination and actual illumination, determine appropriate remedies to adjust illumination and automatically control, and adjust illumination to effect those remedies if desired. Associated software, measurement and control devices, for example appropriate accessories for calibrating the measurement devices, collecting and controlling measurements, analyzing measurements and comparing them to established criteria. The systems and methods can also calculate expected scene illumination based on geographic location, altitude, time of year and day, and weather or other environmental factors, and provides analysis and reports to allow the user to assess scene illumination and plan for in-production or post-production correction of video or film images.
