Photographic geography problem

1. The photos of sunrise and sunset are easy to distinguish.

Anyone who has seen the sunrise knows that there is usually a layer of fog on the ground before sunrise. This kind of fog can be seen on the water, on the mountains and even on the flat ground. This is because when the sun just rises, the temperature rises gradually from the lowest point. When the temperature is low, there must be water vapor in the air. In the sunset photos, the ground temperature is so high that it is impossible to produce such fog near the ground. On the contrary, in the sky, as long as there are clouds, you can see the yellow-red light reflected by these clouds. This is the sunset glow, and you can't see such clouds at sunrise.

Sunrise and sunset also have obvious differences in the color of sunlight. At sunrise, the sunlight refracts far through the air layer, and the color is as red as blood, and the whole sun turns into blood red. People can see the sun directly above the ground, which is not very dazzling. When the sun sets, the sun is still very strong, and even if you are close to the ground, you can't look straight. The whole sun is golden yellow, at least with yellow red.

As for whether we can judge the base from the scenery attached to the photo, it is difficult to judge other scenery except early fog and sunset. Unless shooting in the meteorological observatory, there is a benchmark to indicate the direction, but shooting in the forest can be judged by the roughness and smoothness of the bark. That's south, and that's north. It is really possible to make a correct judgment on the north and south from these references. Then, in the photo, everything that is south on the left and north on the right is sunset, south on the right and sunrise on the left.

According to this, we can also judge the sun in the painting. Because the painting is painted by people, it is better to judge whether it is sunrise or sunset from the yin and yang sides of the reference object. The front is south and the back is north. Sunset is the sun on the left, the shadow on the right and the sunrise on the other side.

3. Because of the climate in the south, rivers and lakes are generally dense and animals appear, so the analysis is the south.
