Shooting skills: light in portrait shooting

  For portrait photography, it is always inevitable to shoot portraits in natural environments. The ever-changing combination of natural light and ambient light creates a wealth of possibilities for portrait photography. How to find the ideal light environment to achieve good light effects and render the atmosphere? Let’s take a look at the use of light in portrait shooting.

   First of all, the common light environment in portrait shooting is smooth light. In a light environment, the brightness of the characters is often greater than the brightness of the background. But if the light is too strong, the portrait itself is easier to overexpose, then you can adjust it through metering or exposure compensation. Let’s take the Nikon Z 7 as an example. In the case of low light ratio, matrix metering can be used for metering and shooting, so that you can get a more accurate exposure.

   If you encounter strong light, you can use center-weighted metering or spot metering for photometric shooting. When using the central spot metering, the camera will meter the entire screen and assign the maximum weight to the center area of ​​the screen, while spot metering will center on the current focus point and measure approximately 1.5% of the entire screen. Metering. These two metering methods can be selected according to the composition of the portrait shot. Or use matrix metering and reduce exposure by reducing exposure compensation.

  Backlight and side backlight are also common light environments in portrait shooting. In a backlit environment, the human subject will be between the light source and the camera. Although the light source will illuminate the environment, the character is in the dark. Although there will be contour light to illuminate the character, the details of the main body of the character are less, and the light and shadow of the face cannot achieve the desired effect. Side backlighting is a certain angle between the three elements of camera, character, and light source. The contour light will appear on the side of the character. The details and levels of the character are more abundant than the backlight, and it will be easier to use than the backlight. .

   Both of these light environments can be shot using spot metering. When metering, you need to meter the face to ensure accurate exposure of people. For a completely backlit environment, if you want to get a normally exposed person, the background is very likely to be overexposed. If you need to expose both the background and the person normally, you can try to use artificial light sources to fill the person alone or use the light reflected in the environment Fill the character’s face with light to balance the character and the background light.

   In addition to the above-mentioned light environment, scattered light is also a common light condition in nature, often appearing in cloudy or cloudy scenes. In the scattered light, the light will evenly illuminate the ground, and the excessive light will be softer. At this time, different metering modes will have less influence on the screen exposure. In this case, matrix metering is generally used.

   When shooting portraits in natural light, not only light, but also the level of shadows must be considered. Only by choosing the corresponding light intensity, light source direction and appropriate shooting time for different subjects can you Natural light plays a greater role in shooting.
