How to use the camera to get the best effect of 3D renderings

Look at a few renderings. If you understand the principle of perspective, you can find the horizon line (you can see that the objects in the pictures are all large near and small, and the distance is small in the end. As small as one or two points, this is one-point perspective and two-point perspective, and the horizontal line between this one point or two points is the eye level), and the height of the eye level is the height of the camera, usually a house 1/3 of the total height (close to the golden ratio). The total height of today's houses is generally 2700mm, so your camera should be set at a height of 900mm (if you don't understand, you can understand it later, but you can remember that the height of the camera is generally between 600--900MM). As for the angle, the angle of the camera should not be too large. You can use the default 24mm lens. If the angle of view is too large, the room will feel empty. Framing mainly depends on what you want to express. There is no constant for this. Just point the camera towards whatever you want to express. Looking at the renderings will help improve the camera setup.

I wish you success!
