Cam Guides Pro is an add-on that provides a comprehensive suite of composition overlays directly within the Blender viewport. It features over fifteen professional composition patterns, including the Rule of Thirds, Golden Ratio, Fibonacci Spirals, leading lines, and various geometric setups. Users can interactively place focal points and vanishing points to align their scenes according to specific compositional rules.

The tool natively includes over fifty predefined aspect ratios covering cinema, television broadcast, and social media formats. It supports per-camera configurations, allowing users to maintain different guide setups for multiple cameras in a single scene. Additionally, the add-on includes broadcast safe area visualizations, custom reference image overlays with blend mode support, and a library of presets for common shot types.
