How to shoot portraits with location flash

When shooting, the flash will measure the light compensation according to the shooting distance and ambient light, and then complete the accurate light compensation. Aperture: F2.8 Exposure time:110s Sensitivity: ISO 100 Focus: 95mm In the twilight, the models in the park are full of flash lights. Method 2: Backlight calendering highlights the picture. People flash can be used not only in dark environment, but also in portrait creation on sunny days. When shooting a portrait in backlight, because the background is too bright and the face is in shadow, no matter which exposure combination is used, there will only be two situations: the sky is exposed correctly, the face is dark or the face is exposed correctly, but the sky is pale. In sunny days, high-power flash combined with exposure control is used to darken the sky background. Aperture: F8 Exposure time: 1/400s Sensitivity: ISO 100 Focal length: 2 1mm At this time, the former exposure combination can be adopted, because the perfect exposure background and the brightened characters can be kept in harmony by using flash to make up the light and exposure with slow flash. Sometimes, in order to create a certain effect, through the adjustment of exposure value, the daytime background can be well darkened. Technology 3: slow flash synchronization technology makes the background perfect. The combination of perfect background exposure and just right character flash is the famous slow flash synchronization technology. Slow flash synchronization is a common technology in night portrait and flash photography. Although the flash can make the subject get enough light, because the flash can't illuminate the background behind the character, it often happens that the subject gets enough light and the background is not exposed enough, and it is dark. Slow synchronous flash is an effective method to solve this problem. Its basic principle is that the setting of exposure value has nothing to do with whether the flash is turned on or not, but with the shooting environment. After the flash is turned on, the camera is still exposed for a long time under the basic environmental exposure. In this way, the main body can get enough supplementary light through the flash and the background can also get enough exposure. Taking portrait photos synchronously with slow flash in twilight can ensure the correct exposure of background and characters. Aperture: F4 Exposure time: 1/50s Sensitivity: ISO 100 Focal length: 17mm This photo was taken in a low light environment at sunset. Perfect background exposure not only shows the color of the sunset, but also includes the sea dyed red by the sunset. After proper exposure, the people in the foreground of the photo present a perfect picture effect.
