“…The illuminance mainly depends on the sun movement during the day and the permeability and thickness of the cloud layer. [1][2][3][4][5][6][7][8][9][10][11][12] This article analyzes the possibility of measuring the sky luminance distribution using the SkyWatcher Virtuoso automated system, which was originally used for astronomical observations. However, it has the ability to mount other measuring devices and can be manually controlled or programmed according to the assumed algorithm.…”

“…The different spectral sensitivity characteristics of the rods and cones, together with additional mechanisms related to changes in pupil size, allow for a wide range o f adaptations in the visual process to changing light conditions that occur in natural light. In lighting technology similar mechanisms of change are accomplished in smart lighting systems [7][8][9][10][11][12][13]. The three types of cones that are responsib le f o r producing visual impressions in seeing are characterized by different spectral sensitivity ranges, which allow us t o perceive colors.…”

The text presents differences between the mechanism of seeing and recording images and potential sources of errors in color reproduction in recorded images. The measurements show that despite the relatively high values of indices (Ra, Rf i Rg) not all tested lamps are suitable for use on a photo set, as indicated by the value of TLCI index. The lighting requirements on a film set prioritize the quality of color reproduction, even at the expense of reducing the Luminous efficacy of a source (LES ) value. Full Text: PDF ReferencesL.T.
