How to shoot an environmental portrait in a big scene

The distortion of wide-angle lens appears more at the edge of the picture and near the lens vertically. As long as the figure is slightly close to the center of the picture and properly away from the lens, the deformation of the subject will be effectively controlled. The lower part of the rest of the picture is used to allocate the foreground and the upper part is used to exaggerate the sky. The foreground application of wide-angle environment portrait is very important. Thanks to the strengthening of the perspective law of the near big and the far small, the foreground will greatly promote the three-dimensional performance of the picture, and the overall picture looks very spatial. The ground as the foreground is a good choice. Of course, I mean the dark ground. Plane visual art has a * * * composition law, the foreground should be dark and the details are slightly lost, and moving objects cannot be used as the foreground of the picture. The purpose of these creeds is not to grab the attraction of the subject in the picture, on the other hand, it can enhance the perspective effect of the atmosphere.

Atmospheric perspective is also called tone perspective or tone perspective in photography. In order to be more realistic and objective, it is necessary to strengthen the third dimension with perspective. It is the law of line perspective that the near is big and the far is small, and the wide-angle lens and the proximity to the foreground are easy to strengthen. In addition, it can well reflect the three-dimensional space under the conditions of near darkness and far brightness, near Qingyuan blur, high near saturation and low far saturation, and is defined as atmospheric perspective. The naming comes from the formation principle, and the air contains a lot of scattering media, which leads to the above results.

Close range and small depth of field

There are essential differences between the foreground blur caused by atmospheric perspective and the depth of field Jiao Wai blur. The former is caused by air medium, and the latter is the large aperture imaging characteristics of optical glass. Wide-angle lens itself has a great depth of field, and the regular use of apertures, such as F4 and F8, can make the clear range of the scene far enough. Wide-angle lens with large aperture is more for hand-held shooting in low light than for seeking small depth of field. A wide-angle lens will have a small depth of field only if it is very close to the foreground. Although it is necessary to be a little close to the foreground in environmental portrait creation, it should not be too much.
