How to use up when shooting night portraits outdoors?

In fact, outdoor night portraits are generally considered to be difficult to shoot. The biggest problem in shooting night scenes is the complicated lighting environment. The dim light outside at night will prolong the exposure time of the camera. If you don't have a tripod at hand, it's easy to shake. Although the flash is easy to use, it can only illuminate people, but the beautiful background can't. Even if the film is clear, it has no aesthetic feeling. Therefore, if you want to take a beautiful portrait at night, the key is to use it up. Here we need to talk about our flash. If you are not a professional photographer, you probably won't bring a special flash when you go out at night. If you want to show the background and characters clearly, you need to use a flash mode called slow synchronization (or slow synchronization). When we use slow synchronous exposure, the person in front of the lens is illuminated by the flash, while the background behind the person is fully exposed by extending the shutter time. In this way, we can get clear and bright photos of people and backgrounds. It needs special explanation here: when shooting in slow synchronization at night, you must explain to your friends that when taking a picture, the flash flashes, don't move the position immediately, and you must keep your posture for a while, because although the flash has flashed, the shutter is still exposed, and the photo may become blurred if you move at this time. Having said this most important point, let's talk about several other points that need attention: 1, the setting of night shooting is more complicated, so don't expect automatic file. If there is a scene mode of night portrait, you can try to take a few pictures to see the effect. If the effect is not good, then choose aperture priority or full manual setting, and choose average metering mode and central focusing, so as to focus more accurately. 2. Turn up the aperture and improve the ISO. What is said here is that if there is no tripod, only these two methods can reduce jitter. Of course, the larger the aperture and ISO, the better. Ultimately, the quality of the image should be considered. If the exposure is insufficient, we can improve the brightness of the picture by simple PS processing, but if it is jitter, PS cannot handle it. 4. Let's talk about anti-shake. It is better to have a tripod. No, don't be too confident about your "iron fist". It is best to put the camera in a stable place and take a selfie after two seconds, which will greatly reduce the stability of the camera. Body, bicycle backseat or railing platform can be used. The difficulty of night scene shooting lies in its complex lighting environment.
