How to play with the camera in 3D to make the space bigger? . The living room is quite large. I look smaller when I play with the camera. . Expert help

Setting up a camera in a large indoor space is mainly to consider how to reflect the openness of the space. There are several ways. One is to raise the height of the target point appropriately, that is, to make people look up, which can reduce the proportion of the ground, let the space above see more, and the whole space will be more open. Another way is to raise the position of the camera and the position of the target point, which is equivalent to a person standing in mid-air to see the whole space, so that the space you see is open.

The focal length of the human eye is 43mm. Supposedly, in order to be realistic, the focal length of the camera in the rendering should be 43 mm. But if you use a camera with a focal length of 43mm, the picture will be narrower. In the view of 3dmax, the camera angle is static and the observation angle is constant. The less we see, the narrower the space is than what we usually observe. Therefore, it is necessary to appropriately reduce the focal length, that is, increase the viewing angle. Generally speaking, the focal length of the lens is set between 28 and 35 mm, which can make the building have obvious perspective or see more space indoors, and the focal length should not be set too small or too small, resulting in too obvious perspective deformation and giving people an unreal feeling. Between 28 and 28-35 mm, the human eye feels real, not narrow, and closer to the feeling we usually observe.

When setting up a camera, we should consider the height, focal length, angle and space atmosphere. Generally, a large space with a height of about 1.5M can appropriately improve the viewpoint and target point. The focal length of the camera is preferably set between 28 and 28-35MM. When setting the angle, we should not only reflect the main design elements, but also pay attention to different spatial atmosphere. A serious space can choose a symmetrical angle, and a relaxed space can choose an asymmetrical, changeable and vivid angle. In addition, the picture should avoid vertical line segmentation. Also pay attention to adjusting the density relationship of the picture.
