Light ratio effect of portrait photography

The light ratio function of portrait photography is as follows:

1, you can adjust the amount of light entering the lens.

For example, domestic kittens always shrink their pupils into a line during the day, and at night they automatically make a round hole in Zhang Kaicheng. So in the same way, when taking pictures, the aperture should be narrowed when the light is strong, and the aperture should be opened when the light is dark. That is to say, the smaller the F value (other parameters remain unchanged), the more favorable it is for shooting at night.

The adjusting ring on the rotating lens or the knob on the digital camera body is used to adjust the aperture size.

Step 2 determine the depth of field

The most important factors are small aperture (large aperture value), deep scene, large aperture (small aperture value) and deep scene! For example, nearsighted friends, if they don't wear glasses, always habitually squint at things, so they can often see things clearly. To use photographic terminology, this is called: narrowing the aperture (pupil) and increasing the depth of field!

Application of aperture:

1. In general, in order to highlight the subject when shooting portraits, it is often necessary to blur the foreground and background. At this time, a large aperture should be used to control the depth of field.

2. In low light or at night, if there is no tripod, you can only shoot with a camera. In order to get a better picture effect, you should use a large aperture, so that you can shoot at a speed not lower than the safety shutter (when the speed is lower than the safety shutter, the effect is not good).

3. When shooting a moving object, a large aperture is beneficial to cooperate with a high-speed shutter to "solidify" the moving object.

Portrait photography skills:

1, take fewer big photos in the big environment.

If you take photos in outdoor environment, such as flowers, grasslands, Woods, the sea and other places, I suggest you take fewer big photos. If the screen is full of faces, it will not only highlight the shooting environment and atmosphere, but also enlarge some small flaws on the model's face.

2. Make good use of light and shadow atmosphere

If you want to present the photos more advanced and textured, the use of light is essential. Choose to shoot in the early morning or evening. At this time, the light is very soft, which can not only create the atmosphere of the picture, but also emphasize the outline of the character at a suitable shooting angle.

3. Don't forget the simple background

If the use of light and shadow is a little difficult for beginners, you can also take a simpler and more convenient method, that is, choose to simplify the shooting background, highlight the characters, and shoot simple and beautiful visual effects.

4. The prospect of joining is even more dreamy.

The level of the picture is also one of the key elements to take high-level portrait photos, which makes the picture present three levels: foreground, middle and background. It can better present the three-dimensional sense and layering of photos, and the combination of reality and reality can make photos more beautiful, romantic and dreamy.
