Who said you can take pictures with light?

Alfred Stiglitz, the "father of modern art" in America, said: Where there is light, you can take pictures.

The effect of a photo depends on the light and shadow. A photo without light and shadow can be said to have lost its soul. Gray photos bring only lifelessness and lifelessness, and can capture the two spirits of light and shadow. Even the dead will suddenly become alive, because light and shadow give the soul.
