First, when shooting night scenes, if the aperture is too large or the ISO is too high, it is easy to form noise and seriously affect the image quality. Because tripods are generally used for shooting at night, they can be exposed for a long time. Choosing a small aperture plays an important role in improving image quality, and it is easy to form beautiful starlight for lighting. If allowed, the ISO is also lower.

Second, both high ISO and large aperture are beneficial to the exposure value enhancement of photos, so using high ISO and large aperture can relatively shorten the exposure time, which is beneficial to snapshot. However, to what extent ISO is large, we should pay attention to the balance between ISO and exposure time, which is not only beneficial to capture, but also does not affect the image quality, so we can only rely on our own exploration.

Third, the exposure time is short, which is beneficial to capture moving objects. Generally, it is better to set the time within 1/300 seconds, which depends on whether the light is sufficient and whether the aperture can be larger.

Fourth, the use of high ISO is also to increase exposure, and the use of small aperture is to improve image quality. In fact, this practice remains to be discussed, because the ISO is too high and the noise is bound to be serious. Looking farther depends on natural conditions, such as sunny weather after rain, good air permeability and sufficient light, so that you can use low ISO and small aperture, and the picture quality will be good. If the weather is bad, it is very reluctant to take a long-term view only by relying on ISO and aperture.
