Why don't cameras look good at night?

The main reasons for taking pictures at night are:

The problem of inaccurate exposure: to take good-looking photos, the exposure should be as accurate as possible, and the light is dim at night. Generally, the performance of cameras in weak light is mostly poor. Under the condition of low light, due to the simple metering system and the limited working range of shutter and aperture, the exposure is often inaccurate; Professional cameras often have pictures that are not properly exposed under low light conditions-also because the photographer's position and method of metering in operation and use are inaccurate.

Blurred picture: Exposure in weak light often takes a long time. Even if a tripod is used, it is often caused by accidental vibration, shutter vibration, mirror vibration of SLR cameras, wind blowing and other reasons. Even if the flash is used for instantaneous lighting, there are still problems such as the subject moving again during the continuous opening of the shutter, resulting in long-term exposure of the photo.

Problems in using the flash: the distance between the camera and the subject exceeds the flash index of the flash, the projection range of the flash does not match the lens, the proportion of the subject point picture is small, the background distance is too far, the extreme color of the background is black or white, which interferes with the automatic flash TTL metering, and the manual flash setting is incorrect, which eventually leads to uneven picture illumination and inaccurate exposure of the subject; Or, although there is no problem in operation, metering and flashing, after the flash illuminates the subject normally, the subject keeps moving in the process of opening the shutter, which causes the problem of factors dragging the virtual shadow and eventually leads to the virtual photo.

Judging from the appreciation needs of most people, the color of the photos taken at night is relatively single, which is easy to appear monotonous compared with the color photos taken every day, and it is also a subjective factor that affects people's subjective judgment.

In a word, night photography is difficult and requires more equipment, time and knowledge. More importantly, we should shoot more, remember more, summarize more, and improve the level and skills of night shooting. Subjectively, we should also treat the photos taken at night realistically and correctly.
