In the end, what angle and light are the most authentic self when taking pictures, or what brightness is the most authentic self when looking in the mirror, and I feel myself every time.

A "good" photographic work can not only make people "see clearly" what they have shot, but also make people truly "feel" the objective existence of the subject. In addition, a good work should also let the viewer understand the thoughts and feelings that the photographer wants to convey through photography.

To master and control the use of light skillfully, we need to know light first. In science class, we all know that light is actually a kind of radiation, which can pass through some medium objects, such as water, glass, thin plastic sheets and so on. Or refraction of light occurs on some objects. Due to the different properties of the subject, there will be different phenomena such as reflection, refraction and projection. These different performances will directly and indirectly affect the effect of photography.

The effect of frontal light is hard, which will form a strong spot on the face and the shadow is obvious. The light overhead can create a very sacred feeling, just like an angel arrival.

Photometry usually highlights the outline of a person's face. Form a shadow on the dull face area on the other side. If you need to reduce the contrast, you can use side light.
