What is glossiness?

Glossiness is how shiny or smooth something looks when light hits it.

Imagine you're playing with a ball, one is super smooth like a marble, and the other is bumpy like a tennis ball. The marble looks really shiny because it reflects the light evenly, making it seem almost like it's glowing. That’s glossiness in action!

When light hits something smooth, it bounces off in the same direction, creating a clear and bright reflection, just like when you look at a mirror. But if something is rough or bumpy, the light scatters in different directions, making it look less shiny.

Think about your favorite crayon, if you draw on paper with a crayon, it's not super glossy because the paper has little bumps that make the light scatter. But if you shine a flashlight on a smooth glass, it reflects the light like a mirror and looks really glossy!

So glossiness is all about how much light bounces back evenly from a surface, the smoother it is, the glossier it looks!
