How to take pictures under the strong light of shadowless lamp in operating room
Although natural light has the advantages of being true and natural, it can properly express the scene atmosphere when shooting, but natural light is not perfect and cannot appear in every place where lighting is needed. Therefore, adding flash can help make up for the shortage of natural light and improve the quality of photos. When you master the technical skills of flash and integrate them into your future creation, you will find the same content and the same picture, but the work is "borrowed from the next level".
First, outdoor portraits need to be filled with light during the day.
Don't think that you only need to use a flash when the light is dark. Sometimes you must use a flash to fill the light when the light is sufficient. In one case, there is a great contrast between the subject and the background when shooting against the light. If the subject is exposed, the background will inevitably be overexposed, the background will return to normal, and the subject will be underexposed. At this time, you need to fill the light with a flash.
The shooting environment was in the sun at 3: 30 in the afternoon. Although the ambient light darkens with the setting sun, the light is still bright due to the influence of backlight. This man is backlit, and his face is very black. When taking this photo, measure the environment first. The measured data is the aperture F3.5 and the shutter is 1/250. After the measurement is completed, set the camera to M, set the aperture shutter, turn on the flash, TTL mode, and reduce the output by 1.5. Finally, the finished product drawing shows that people's faces are exposed normally and the environmental atmosphere is also obtained.
Backlight draws a circle of warm lines around the girl's hair and clothes, which is isolated from the background and highlights the main body of the character. The front flash fills the light. When shooting a composition, pay attention to covering a part of the main body of the sun with the subject to avoid too much glare.
Generally, it is not easy to shoot portraits of sunny days, blue sky and white clouds in the backlight environment, because the light difference between the subject and the background environment is too big, and it is not easy to take into account the normal exposure of both. If the face of a portrait is used as the basis of photometry, the background will be overexposed and there will be no details. If the blue sky is used as the basis of photometry, the face of the portrait will be underexposed and even become a silhouette.
