3 classic example techniques: how to use outdoor flash to take portraits

Technique 1: Brighten the subject in low light. Using flash in low light means using TTL flash technology to brighten the subject when the ambient light is dark. When shooting, the flash will calculate the amount of fill light based on the shooting distance and ambient light, thereby achieving accurate fill light. Aperture: F2.8 Exposure time: 1/10s Sensitivity: ISO100 Focal length: 95mm At dusk, use a flash to fill in the light of the model in the park. Technique 2: Backlighting to highlight the characters in the picture. Flash is not only used in dark light environments, but can also be used in portrait creation in clear daytime. When shooting portraits with backlighting, because the background is too bright and the person's face is in shadow, no matter which exposure combination is used, only two situations will occur: the sky is correctly exposed and the person's face is dark, or the person's face is correctly exposed but the sky is flat Pale. On a sunny day, use a high-power flash combined with exposure control to darken the sky background. Aperture: F8 Exposure time: 1/400s Sensitivity: ISO100 Focal length: 21mm At this time, the former exposure combination can be used, because the flash is used to fill in the subject of the figure, and at the same time combined with the slow flash synchronization exposure, the background can be perfectly exposed Exist harmoniously with the highlighted characters. Sometimes in order to create a certain effect, by adjusting the exposure value, you can also darken the background during the day.
