Summer has come, the sun has become terrible, even the time of taking pictures has to change with time. The weather is hot and I don't want to go out. The outside light is too strong. The backlight or the ugly hard shadows are taken. How can we take good pictures in the fierce sunshine? ? Especially when the light source is behind the model, it is easy to take full black or white background photos of the subject. It is necessary to study how to express the details of the subject and background clearly.
Of course, backlight photography does not necessarily mean that the light source is just behind the main body. We can generally understand that the light source appears in a range behind the main body, while the front of the main body is in the backlight area. If we need to take a picture in a position with a direct and glaring backlight, because the light is directly injected into the lens, there will probably be glare in the picture. The glare has two sides. On the one hand, it may interfere with the expression of the picture or may cause the picture to lose details, but it may also make the picture look. It's more interesting and dramatic. How to understand the role of glare in the picture depends on our own understanding and needs.
In order to make the picture without glare, we need to block the path of direct light into the lens. The most effective way is to find a shield on the lens, such as shooting indoors and outdoors, or shooting in the shade of trees. Shadows can block unnecessary light and make the image less blurred.
The dynamic range of the camera itself may be difficult to achieve if the front of the model in the backlight environment can be adequately exposed, because the front of the model will be obviously under-exposed if the strong light on the back is measured, and the background will be over-exposed if the front of the model is measured. At this time, we need to use some external supplementary light sources, such as the supplementary flash, so that the model's face can be exposed correctly and the under exposed part of the image can be illuminated by the flash.
Ideally, the supplementary flash should not be an external flash directly oriented to the shooting object. The front plane lighting will make the model lose the stereoscopic sense. The supplementary flash should have enough freedom to adjust the angle and intensity of the light on the model's face.
In fact, for most backlight photography, we all want to take a good silhouette photo. Sometimes we can tell stories through silhouettes. Because of the strong contrast of brightness between the foreground and the background, we can not see any details in the main body of the foreground. We can only see a dark outline. We can not see their expressions, so we can not perceive their emotions. Everything needs our imagination to guess the possible story.
Because all emotions are possible, this is one of the reasons why some silhouettes are so fascinating. By forcing the viewer to think through the missing details, the viewer will develop different stories because of his different ideas.
First of all, we need to understand that the formation of silhouette is due to the contrast between the subject and the background beyond the dynamic range of the camera. If the background is exposed correctly, the subject will be underexposed. If the subject is exposed correctly, the background will be overexposed. So one of the basic requirements for taking silhouette photographs is to put the subject under the strong light source, so that the subject is facing the strong light source.
If there is no deliberate use of artificial light sources, the best place to shoot silhouette is in the morning or evening, the sun near the horizon, can be used as a light source in the background. Exposure to sunlight can darken the image as a whole, making it easier to create contours, and even if many levels of exposure are reduced, the sun will not be underexposed, let alone produce unpleasant highlights. And in this period of time, the light is soft and golden, which will produce a beautiful golden halo around the body.
When shooting silhouettes, the geometry and guide line of the toned image will be enhanced in the picture. Try to arrange the elements in the picture, use the guide line to guide the viewer's vision to the main body, and ensure that there are no unnecessary elements behind the main body will interfere with the overall outline. Unless you want to create on your own initiative, a few branches behind the subject may make you feel that the subject has become a spider.
One of the easiest ways to avoid background interference is to lower the camera's angle and shoot from top to bottom, so that the perspective upward obliquely turns the background of the subject into an empty sky and minimizes the interference. Most of the silhouette photos that come out directly from the camera may not be as good as we like, because the camera is too smart, smart to always want to make some smart, want to get a perfect silhouette photo, or need to adjust later, increase the contrast between the main body and the background, adjust the tone.
