Besides the embodiment of the creative design, both the 3D rendering and actual photographs hope to achieve is that the aesthetics of the graphs will resonate with all viewers. No one can deny that camera angle plays a vital role in this. When deciding the camera angle, we should not only pay attention to the main elements of the design, the spotlight should be turned on the tones of different spaces as well. An overall symmetry will be used to present solemnity, while the asymmetrical and lively design is a wise choice for flexibility. A complete symmetrical graph is a must-not, and more attention needs to be drawn to the intensity of the graph. In all, a clear goal is a must for setting up a project: what does this 3D rendering hope to achieve?
- For exterior projects, is the spotlight the building itself? The overall plan? Structure of buildings? Or the landscape?
- For interior projects, which particular area is the spotlight for the design and layout?
In fact, it doesn’t matter whether it’s interior or exterior projects, designers need to provide supporting materials, such as CAD files or SketchUp models, explicating the design details and articulating the desirable result that you want to achieve. Here are some camera angle suggestions for reference:
- For tabletop still object, 50-130 mm focal distance is commonly used. It’s better to turn on depth-of-field effect, with 10 to 30-degree high angle shot, 5-20 times subject distance.
- For interior renderings, 40-80 mm focal distance is commonly used, with +5 to -15 degree shot. The subject distance depends.
- For exterior renderings, 30-50 mm focal distance is commonly used, with 5 to 40-degree low angle shot or 20 to 35-degree high angle shot. Moving camera to capture the space when the subject distance is set at 10-50 times.
Camera Angles for Exterior Design
The first step is to confirm the camera angle of the 3D rendering, including eye-level view, semi-aerial view, and aerial view. Next, it’s to identify the design highlight: the building itself, landscape, or other details? As for the exterior human eye, it is a fairly neutral shot angle, stimulating a standard human vision and thus present visual information through a familiar viewpoint, which refers to 160-180 cm height but not over 200cm. This angle shows the most important part of the building that we expect to see in real life or what the client cares most about. When the model built by CG artists are finished, the building can be viewed from various viewpoints by the camera, which is as same as the cameras we use in our daily life. To place the camera’s center point at the building, you can move or rotate the center point to create the perfect angle for your design.
Regarding the semi or aerial view, they follow the same rule of human eye when it comes to angle creation. Semi-aerial view shots at 200-1500 cm camera height. If there’s a lake in front of the building, the angle will set above from the lake surface, so that the reflection with ripples and the building itself create a vivid and dynamic view. Aerial view, is a completely different point of view, which has a camera height of more than 1500 cm. In this view, it is shown from directly above with a clear view of the buildings and the surrounding context.
Camera Angles for Interior Design
First, it’s to decide the space where should be spotlighted in the 3D rendering and confirm the camera’s direction inside the room. Based on the requirements of the clients and the built model, AIMIR will provide several options for checking the angles. The major concern of the interior rendering is to make the room look more spacious than it actually is. Following are a few tips about creating an interior angle.
- Enlarge the space by lifting the object. In this way, reducing the ground space in the rendering so the whole space looks wider.
- Elevate the camera angle, just like viewing the space at the higher space. This has the effect of diminishing the subject, making the space wider.
- In some cases, clients offer a relatively confined space, but they would like to show the spaciousness. AIMIR will adjust flexibly with a camera outside the room. The camera behind the wall will show the room from a more complete point of view.
The focal distance of human eyes is 43 mm. Unfortunately, this focal distance cannot be used in 3D renderings because the back of human eyes is curved, the perception of the 3D rendering will be quite restricted. To be more specific, the view is fixed because the camera in 3D MAX is static, thus, the space seems to be narrower. Therefore, the focal distance should be set among 28 mm to 35 mm. This range is very close to human eyes’ so that there won’t be any distortion. In general, when setting the camera angle for interior 3D renderings, height, focal distance, angle and spatial atmosphere need to be taken into account. The camera height will be 1.5 meters in most cases, with variations in commodious spaces.
Other Camera Angle Deciding Tips for Interior Design
- Do not become obsessive with the wide-angle camera. Distortion is the only thing wide-angle does for interior designs. Unless there are close subjects. Wide-angle works amazingly in confined spaces and close subjects.
- Small aperture (f/14, 15, … even 32) is recommended if the whole room needs to be presented clearly. On the contrary, a large aperture of f/2.8 or f/1.4 is much desirable for photos where subjects are isolated. It results in a large amount of both foreground and background blur.
In summary, the camera angle is a contributing factor in making a marvelous 3D rendering. On top of that, the critical part still starts from a good design and timely communication between two parties. There are many tips you should keep in mind when creating the angle.
