It is known as brightness to light issued or reflected For a body. The term may refer to emitted luminous flux or to the color clarity . For example: “Look at the shine of that jewel! It is spectacular", "This morning I locked the floor so that it has more brightness", "I'm going to increase the brightness of the TV since I can't see clearly".

In the case of screens, we usually associate the term brightness to that property of the image which allows us to see objects more clearly, although modern technologies have made this concept more complex.

One of the problems of increasing the brightness level in a conventional television is that the colors begin to lose intensity and to look "washed"; in a nutshell, they get closer to the target, something that in no way occurs in real life. However, companies like Samsung they strive year after year to ensure that their panels allow the least loss of color despite the increase in brightness, something that can be seen in the series called QLED .

The brightness is usually associated with an object that is new or what is cleansed and shimmering . A car 0 km It has shine: it does not present the stains, scratches and scratches that are generated with use. As the weather , the vehicle will lose that bright appearance.

In the field of astronomy , the brightness is associated with the brightness . The physical property that refers to the amount of energy emitted by a celestial body per unit of time is called luminosity. According to the distance we are from the body in question, we will perceive a greater or lesser brightness. He surface brightness , meanwhile, is the apparent brightness of a galaxy or other astronomical object with considerable extent.

The idea of ​​brightness can also mention the way in which light interacts with the surface of a mineral . This brightness depends on the absorption of the colors by the mineral and its refractive index.

Brightness, finally, is used symbolically to name the show or the success of someone or something: "The brightness of the Swiss tennis player remained unchanged for almost a decade", "In a dull match, the German team won the Italian team by 1 to 0", "The critic said that viewers will be surprised by the brightness of the young actor in his new film".

The brightness of a person is always its most remarkable aspect, although it does not always combine with a personality fury. In fact, the brightest people are usually the most unhappy because of their difficulties to be understood by others. Behind many geniuses of art and science there are beings that do not support life, who feel trapped in a story of which they must be the protagonists despite not having had the possibility to choose this role. We could say, figuratively, that the magnitude of brightness is always directly proportional to that of shadow.

Of course, it is in the hands of society to route bright children adequately and constructively to avoid considering their talents a torture from which they cannot escape . The closest parents and relatives are the first who should notice the brightness in these very special individuals, but it is more common for teachers to have the tools to do so. For this reason, schools should be prepared to teach each person the best way to take advantage of their own potential , instead of giving everyone the same content.
