Lens (focal length, field of view)
Choose focal length and field of view to control perspective, distortion, and camera matching in 3D paint-over work.
What it is
In 3D, lens settings include focal length and field of view. Field of view describes how much of the scene the camera captures. Short focal lengths show more space, enlarge nearby objects, and make distant objects appear smaller. Long focal lengths show less space and compress distance.
Select focal length for the shot. A wide lens can make a foreground subject loom and the background recede. A longer lens can make architectural space appear flatter while keeping verticals straighter.
When matching a sketch or photo reference, compare perspective convergence, the size change of nearby heads and hands, and the apparent distance to the background. Adjust focal length and camera distance until the 3D camera matches those relationships.
Why it matters
Focal length affects the scale, depth, and distortion of characters, props, and environments. Weak control can make nearby anatomy or weapons stretch, flatten a dynamic pose, or create mismatched perspective between references, 3D block-ins, and paint-overs.
You can check it when
- ✓Classify a photo or film frame as wide, normal, or telephoto by checking space compression and distortion.
- ✓Recreate a comparable lens feel in 3D and observe whether nearby objects show similar exaggeration or compression.
- ✓Keep a subject the same size in frame while changing focal length and camera distance, then compare the background spacing.
- ✓Check a 3D paint-over base for consistent lens behavior in figures, props, and environments from block-in through final.
