Photographic lighting skills

There is basically no all-black environment. At night, the room usually fills the light outside the window to simulate the natural light projected from the window. In addition, some small lights are used to create a kind of light beam that is not easy to see visually where the light is needed, but it is actually diffused light supplemented by light, and in this environment, it is usually a super-large aperture lens. There are many less exquisite methods, such as darkening, motion tracking, masking and masking in post-production, to ensure that the outline of the subject has enough visual effects and relatively darken the background. The first picture is blue? Another shooting method is to add an ND mirror to reduce the light entering the lens to simulate the black environment. The advantage of this kind of shooting is that it preserves the details of the object and reduces the illumination.

In the second picture, the light is added to the right side of the character. From the background, there is no strong light source on the right side of the characters in the scene, and the light on the face is abrupt. This replacement is mostly reflection compensation, and the light is projected at another angle. The light source is reduced to the illumination compared with the scene by reflection and diffuse reflection, and then projected onto the character. As can be seen from the shadow of the right neck of the character, the area of this fill light is small, mainly for the face, and the height is higher than the height of the character. In addition, it is judged that there is similar supplementary light on the left side of the character, but the illumination is smaller and the area is more concentrated on the head of the character. Look at the contrast between the neck and shoulders. In addition, the upper back of the character should be filled with light. Look at the light on both sides of the hair. There is no light on the left shoulder of the character, but the back of the strap of the character's backpack is bright, so this light is a simulated street lamp, which is much smaller than ordinary street lamps. Moreover, it is estimated that there will be a large diffuse reflection light plate behind the camera to realize diffuse reflection and weaken some light to the front of people. In fact, after the film is finished, it will have to be later, and it may not be possible to shoot very realistic light. As long as the light is sufficient, it can be adjusted later.

Film lighting and photographic lighting are two concepts. The former is to simulate the natural environment as much as possible, and it is necessary to consider all angles of the environment. The latter is to highlight the subject, and generally does not consider the degree of integration between lighting and the environment.
