What is the sensitivity (ISO) for shooting night scenes and daytime landscapes?

Generally, ISO is 100 to 200 in the daytime when there is sufficient light, and 400 to 800 at night.

When shooting in dim light, you can choose a higher ISO sensitivity. Of course, for SLR cameras, you can also choose to use a larger caliber lens to improve the luminous flux. For ordinary digital cameras, because they use a fixed lens, only by improving the ISO sensitivity can they adapt to shooting in dim light, especially when auxiliary light cannot be used.

Photosensitive application

1, low sensitivity (low sensitivity below ISO 100): Generally, low sensitivity will be used in some advertising commercial photography and landscape photography, because low sensitivity can obtain extremely smooth and delicate photos.

2. High sensitivity (above ISO200 is high sensitivity): Although higher sensitivity can improve exposure, there will be obvious noise. With this setting, the importance of the subject matter often exceeds the quality of the image. After all, sometimes the shooting conditions are too bad, and it is better to take a slightly poor quality photo than not to take an image at all.
