How to set ISO, aperture and shutter for night shooting?

If you want to shoot a big night scene and make the picture very clear, you should choose a smaller aperture (such as F22, F 16, etc. ) to get a better depth of field effect, so that the distant view is as clear and detailed as the close-up view, especially the neon signs in the shop window can be clearly displayed, otherwise the neon signs will form a mass of light and look blurred.

If you shoot a smaller object, you can choose a larger aperture, and you can also take a good photo by highlighting the details with a shallow depth of field effect. The light at night is much darker than during the day. In order to ensure the image quality, choose low sensitivity. With a small aperture, the shutter speed will be slower. The slow shutter can take some special photos. If the exposure time is long, you can choose B-gate exposure as needed.

With the improvement of ISO sensitivity, the images taken by digital SLR cameras will be degraded by noise. If the sensitivity is too high, there will be noise in the picture. The lower the sensitivity, the better the image quality. ISO sensitivity can be 50 or 100 to minimize possible premature phenomena.

Techniques for shooting night scenes:

1, shutter speed

Because we shoot in aperture priority mode, the shutter speed is automatically calculated, so we don't need to care too much, as long as the camera is stable. (So we usually shoot with a tripod here. )

2. Hole

When shooting night scenes, I usually put the aperture between F8-F 16 to ensure the small depth of field before and after. As for the specific value selection, it depends on the specific depth of field and the desired effect (such as the length of the car trace, etc.). ).

3, sensitivity ISO

The setting of sensitivity is the simplest, because we don't need to consider the shutter speed, because there is a shelf, so we can only choose the lowest native sensitivity, such as ISO 100 or 64, to ensure our best image quality.
