Luminosity – direct light source

Introduction Luminosity is an important indicator of the quality of light and is defined as the degree of brilliance, which is determined based on the ratio of the brightness of the sample to the brightness of its background. It characterizes the brightness of light and is used in areas such as lighting technology, film production, photo-video production and many others. In this article we will look at the essence of glossiness, its meaning, measurement methods, causes, and ways to reduce or eliminate increased glossiness.

***Gloss*** is the intensity of the light flux that enters the observer’s eye due to reflection from an object or its surface element and comparison with the intensity of the direct light flux from the light source (direct glare) reflected from the walls of the microscope telescope (reflected glare ) or diffuse reflection from an extraneous light source located towards the observer. A higher gloss index is more favorable (especially for visual inspection).

**Gloss measurement** There are various methods and tools for measuring gloss:

* photometric systems – most common in industry; * sensors - used to measure glare on monitor screens; * “before-after” visualization techniques are based on measurement
