Light, Glory, Objects and Photography

what we usually call light is a physical phenomenon, which is the energy of electromagnetic waves, and electromagnetic waves propagate through tiny photon beams. Some light is visible to our naked eyes, and some light is invisible to our naked eyes.

Photons are all energy, and this energy will generate an electromagnetic field around them. The electromagnetic field of some photons will fluctuate faster than that of others. The greater the energy of photons, the faster the electromagnetic field will fluctuate. Although we can't see the magnetic field around photons, our naked eyes can see the difference between photon energy and magnetic field fluctuation, which is what we call brilliance. Because of the different fluctuations of electromagnetic fields, our naked eyes will recognize electromagnetic waves of different frequencies into various glories, which is also the principle that we can see various glories. Glory is presented by the illumination of light, and only with light can we see the color of objects. We can't see anything clearly if we are in a dark room without light. The white light emitted by the sun is composed of various colors, and the light band composed of various colors is defined as red, orange, yellow, green, cyan, blue and purple.

how is the color of the object formed? When light shines on the surface of an object, it will absorb part of the light, but the light that is not absorbed will be reflected. These reflected colored lights act on our vision, forming the color of the object we see.

We describe specific light in the process of shooting through these three aspects:

We can summarize light, brilliance, objects and photography as follows:

1. Light and color-light is a prerequisite, without light, there is no color;

2. Light and objects-The change of the color of objects by different intensities of light will change the perception of human eyes;

3. light and photography-the consistency between the intensity of light and the height of the subject is the key to whether we can arrange and shoot good works.

So, on the basis of understanding the basic principles of these lights, we continue to practice and explore, so as to shoot our better works.
