What Are Simulated Cameras?
Simulated cameras, also known as pseudo cameras or CGI cameras, are not real working cameras. They are computer generated images and animations designed to look like photographs taken with a real camera. Simulated cameras have become increasingly popular in 3D animation, visual effects, and video game development.
How Simulated Cameras Work
Simulated cameras mimic the properties and behaviors of real world cameras in a 3D graphics application. The software simulates attributes like:
- Lens focal length
- Aperture size
- Sensor size
- Depth of field
- Lighting and exposure
These settings affect the virtual image or scene the simulated camera 'captures'. For example, adjusting the focal length changes the field of view, while tweaking the aperture alters the depth of field. The computer generated scenes or assets are rendered to look like real photos.
Uses of Simulated Cameras
Here are some common uses of simulated cameras:
- 3D animation - To create CG animations for films, television, commercials etc.
- Visual effects - Seamlessly blending VFX with live action footage in movies.
- Video games - Rendering in-game scenes from different virtual camera angles.
- Product visualization - Creating photorealistic renders of products for advertisements.
- Architectural visualization - Making architectural 3D models look like real photographs.
Benefits of Simulated Cameras
Some key benefits of using simulated cameras include:
- Full control over lighting, camera angles and movements.
- Ability to create physically accurate camera effects like depth of field, lens flare, motion blur etc.
- Flexibility to adjust camera settings for desired mood and visualization.
- Cost saving compared to shooting on real cameras, especially for complex scenes.
- Ease of experimentation without film costs or camera limitations.
In summary, simulated cameras provide extensive creative control for digitally photographing virtual 3D worlds and synthesizing photorealistic imagery. They are indispensable tools for many forms of visual media production today.

Choosing the Right Simulated Camera
Selecting the appropriate simulated camera is crucial for achieving the desired visual style and perspective for CG projects. Here are some tips for choosing the right virtual camera:
Match the Lens to the Scene
Wide angle lenses are good for shooting landscapes and architecture exteriors to capture more scene context. For portraits, a 50mm or 85mm standard lens provides a natural perspective without distortion. Telephoto lenses help focus on smaller details from a distance.
Factor in Sensor Size
Full frame simulated cameras replicate modern DSLRs with a large 35mm sensor size. APS-C or Micro Four Thirds simulated cameras have smaller sensors just like their real-world counterparts, affecting field of view and image quality.
Consider Camera Movement
Static cameras on a tripod provide stable framing. Moving handheld cameras generate realistic shake effects. Tracking shots require setting up dolly, crane, helicopter or other simulated camera rigs.
Match the Style
For a cinematic look, use 24fps cameras with cinematic aspect ratios. For a documentary style, go for 30fps or 60fps frame rates and add handheld shake. Higher frame rates are better for slow motion sequences.
Factor in Lighting Conditions
In low light scenes, use high ISO and wide aperture settings. Brighter scenes allow lower ISOs and narrower apertures. replicated lens bokeh and flare effects.
Test Different Angles
Explore low, high, canted, aerial, close-up and other camera angles. For example, a low angle horizontal shot can lend a dramatic perspective. Top-down shots provide interesting overviews of action.
Use Camera Presets/Templates
Many 3D apps provide preset simulated cameras matching real models like Arri Alexa, Red Monstro, GoPro etc. with appropriate settings. These serve as good starting points for refinement.
In summary, consider the scene, movement, lighting and desired style while selecting the optimal simulated camera. Taking the time to test different virtual cameras almost always improves the final visual appeal and realism.
