Salt of the Earth

As an Oscar-winning documentary, "Salt of the Earth" seems to be a tribute to the photographer.

Photography can be seen as a recollection of the origin of words. If the interplay of light and shadow is captured well, it can reflect many things.

The Bible says, you are the salt of the earth. So salt can generally refer to people, but in the documentary "Salt of the Earth", "salt" also refers to mineral resources on the earth.

Brazil is the gold mine of La Pelada. When photographed from an airplane, it is desolate and silent. There is no gold here anymore, but the photos from the past are enough to record the enthusiasm of people at that time. In the photos left behind, there are people all over the mountains and plains. They have dark skin, but they are not slaves. They are all kinds of people going for the minerals. The ladder is made of plants and is extremely unstable. If it falls, the people below will also be injured. There is no way to keep it, but many people are still scrambling to climb up. This seems to have been the case since the distant pyramid era. Looking at these photos, for a moment, I feel like I have returned to the beginning of time. There is no mechanical sound, only the weak and low conversation between people.

Are real slaves gold? It determines whether people are free and independent, generation after generation, or whether humans are slaves?
