Digitale Entfernungsmessgeräte zum Fokusziehen
19 Jahre alt. Geräte und Preise können sich seitdem geändert haben.
Was die Diskussion ergab
- Sonar-basierte Fokusentfernungsmessgeräte wurden von Herstellern entwickelt, darunter Panavision mit ihrem Panatape-System und CE mit dem Cinetape, die Ultraschallhörner verwenden, die Sonarsignale aussenden und empfangen, um die Entfernung zu berechnen
- These sonar systems allow operators to set parameters to ignore certain distances or foreground elements like flags or actors to avoid false readings
- Laser-based focus distance measurement devices such as the Sniper use infrared wavelengths safe for actors' eyes, with some versions including a visible-spectrum aiming laser for setup purposes
- Laser-based systems can provide accurate distance readings on mirror shots and through windows due to how laser light behaves similarly to camera light
- These distance measurement tools are primarily rented from camera rental houses, though some focus pullers purchase them for personal use
- Sonar and laser systems function as checking aids rather than primary tools and can become counterproductive if operators rely on them without maintaining traditional focusing skills
Hängt ab von
- Discussion dates to 2007 and technology may have evolved significantly since then
- Sonar devices can be interfered with by certain environmental factors or foreground elements requiring manual filtering
- Both sonar and laser systems require proper setup, balancing, and power management on camera rigs
- Details about the Sniper's infrared safety and capabilities are acknowledged as approximate by the participant
