| Popis: | In recent years, many software have appeared on the market to evaluate different parameters of lighting. Since the digital image has demonstrated the usefulness of measuring the luminances of surfaces, there are different software that help to evaluate the contrast of surfaces luminance. This paper presents the evaluation of three lighting software in three different lighting situations. Firstly, Aftab Alpha software requires the use of other sophisticated equipment such as luminance meter and reflex camera. Secondly, Fusion Optix software is an application easy to use because it works with a high dynamic range image from smartphones. Finally, Lumin software which reads the content of pixel-to-pixel picture to determine the luminance at each point of a scene is studied. Comparative measures serve to find the differences between the results of software analysis, the actual luminances of surfaces and different light intensities of spaces. This evaluation allows defining advantages and disadvantages of the use of three different software according to the light intensities of spaces. The study suggests that for spaces with low light intensity, the Aftab Alpha software and the Lumin software have a closer correspondence to the measurements. Concerning medium and high light intensity spaces, the Aftab Alpha software presents values near to reality. |
