Camera Matching
Introduction
This module establishes the second anchor: a matched camera. You learn how perspective solving (the fSpy process) recovers a photo's camera parameters from vanishing points, and — through the composed theory references — understand the perspective and camera-matching principles underneath. By the end, a source photo becomes an exactly-placed camera in your Blender scene.

Learning Outcomes
By the end of this module you will be able to:
- Explain how perspective solving recovers camera position, orientation, and focal length
- Perform the fSpy process step by step: load photo, identify horizon, draw vanishing lines, import the solution
- Bring a camera match into Blender and verify it against the source frame
- Recognize when a photo won't solve and what to do instead
Module Contents
This module pairs the practical walkthrough with the underlying theory. Work the steps in order.
The theory: how a camera projects 3D space onto a flat image, and how to read it back — frustum, focal length, the horizon line, vanishing points, and the one-, two- and three-point cases.
You'll learn: Why vanishing points and focal length behave as they do — the model behind every camera match.
The full technique: matching strategies, workflows, and the toolset for matching a camera to source footage.
You'll learn: The complete camera-matching methodology this module's walkthrough is a worked example of.
Knowledge Check
Test what this module covered before moving on. Questions are drawn at random from the module's pool, with immediate feedback on every answer — the questions and the options reshuffle on every attempt.
Camera Matching
Check the second anchor — recovering the camera that took the source photo. Vanishing points, the fSpy process, and when a photo will not solve.
