Photography skills in the dark

First, fill the light and use an external light source or flash; Second, use a tripod to slow down the shutter speed (extend it to enough exposure time), and at the same time try to keep the subject still, otherwise it will not be clear; Third, in the absence of a large depth of field, try to open the aperture as large as possible; The fourth is to increase ISO sensitivity. If you can't fill the light, you can only use the following 2, 3 and 4 methods.

The principle of the camera is the same, try to open the aperture as large as possible (the smaller the number, the larger the aperture, such as f1.8 > F3.5), using high sensitivity and night scene mode, as close as possible to the subject.
