Referenz-Kameras ergänzen meine Hauptkamera mit zusätzlichen Perspektiven für VFX. Sie dokumentieren Lichtverhältnisse und Set-Details, die später für digitale Rekonstruktion essentiell sind.
Secondary camera capturing footage specifically for VFX reference, motion capture tracking, or documentation purposes – records set conditions, lighting, actor performances, and spatial relationships from different angles to aid post-production reconstruction and digital environment creation.
What is a Reference Camera?
A Reference Camera is a secondary camera that captures material for VFX reference, motion capture, or documentation. It complements the main camera with additional perspectives and information for post-production.

Perspectives
Director
Referenz-Kameras geben mir Material für spätere Entscheidungen. Wenn VFX neue Blickwinkel braucht oder Änderungen nötig sind, haben wir dokumentiert, wie das Set tatsächlich aussah.
Producer
Referenz-Kameras sind eine kleine Investition für große Flexibilität in der Post. Die zusätzlichen Aufnahmen können teure Probleme verhindern, wenn VFX-Fragen auftauchen.
