In rainy weather, or in dark places such as indoors or in the Woods, in order to better raise the subject and show the texture of people's skin and clothes, or to lose the shutter speed, it is necessary to fill the light. Flash or reflector can be used according to different scenes when filling light. How to fill the light in portrait photography? First, turn off the flash, measure the shooting with aperture priority method, and check the exposure of the photo. In order to highlight the characters, the picture can be slightly underexposed. Then turn on the flash to fill the light. When filling the light, the flash has two modes to choose from: one is ETTL mode, which allows the camera to determine the output power of the flash, and then make positive and negative compensation whether it is invented or not; Or flash in m mode. Take Canon EX580 II as an example, it can output in the power range of11to1128, and select the appropriate output. The light is in good condition, but the figure is blocked by the branches and leaves of trees, so it is more appropriate to use the reflector: when shooting a scene with dense branches and leaves, the flash can easily illuminate the leaves around the figure at the same time, and the reflector has the upper hand at this time. It is easy to control, just adjust its angle and get close at a certain distance. In addition, because of its soft light, it is not easy to cause eye-catching highlights. Pay attention to the direction of supplementary light, and move the position of reflector back and forth based on the principle of soothing people's faces to obtain the required light intensity. Using a reflector is the simplest way (what to pay attention to when using a reflector), and the consequences are intuitive. Please refer to "1" for flashing operation. Generally speaking, the face of a character is slightly darker than the background and looks more artificial. Since it is location shooting, many times, some elements of the scene become very important and often play a role in deepening the theme. If these main elements are submerged in darkness, they must be full of light. In the picture, the scene light is input from a small window, the brightness is limited, and the prayer wheel is swallowed up by darkness. The portable flash is installed on the warm boots of the camera, and the lamp holder rotates to the left, which can supplement the light of the prayer wheel and the backlight side of the person at the same time, killing two birds with one stone. The advantage of this method is that it is simple to operate and does not need to bring too many lights. The problem is that there is no choice between light and dark areas, and there is a lack of depth. The effect of flash outside the machine will be better. Off-camera flash can make the picture form different light and dark areas, making the light and shadow of the picture more abundant. As far as this picture is concerned, the lamp that fills the light is absolutely hidden, and the lamp holder in the background is easily exposed in the picture. You can put it behind people, or you can take off the lamp holder, install the flashing light on the small seat frame provided by the original factory, and then hide it on the windowsill to simulate natural light.
