Lo que encontró el hilo

• Una plataforma 3D ligera se puede construir a partir de dos cámaras Panasonic DVX-100A con un peso total alrededor de 10 libras, que requieren una placa de acero para el equilibrio en días ventosos.
• El DVX-100A tiene una lente fija no intercambiable con un mecanismo de enfoque interno escalado 1-99, haciendo verdadero follow focus desafiante sin modificaciones.
• Sincronizar el enfoque entre dos cámaras en una plataforma 3D es crítico, ya que incluso las diferencias de enfoque sutil entre las cámaras comprometerán el efecto 3D.
• Fixed focus with depth of field is preferable to attempting manual focus on both cameras simultaneously, especially outdoors with good lighting.
• One approach to controlling dual follow focus motors is using two motors on the same frequency channel with separate potentiometers, though mechanical pot variations can cause slight lens disagreement.
• Alternative 3D capture methods include positioning two cameras at different angles to create split-screen perspectives rather than true stereo imagery.
• 3D footage from compact DV cameras can be reviewed using special binocular viewers where each eye sees a separate LCD screen from each camera.

Depende de

• The DVX-100A lacks standard interchangeable lens mount needed for traditional follow focus systems.
• Synchronizing two separate motor control pots creates slight mechanical variations that may affect focus accuracy.
• The described project's final display outcome was uncertain at time of posting, as it required approval from the artist and museum installation.
• The alternative 90-degree angle approach mentioned was never broadcast in its original form due to production company decisions.
• Experience is limited to specific weather and lighting conditions (sunny, snowy outdoor shooting) with particular depth of field characteristics of 1/3 inch CCDs.
