Camera Settings

To achieve optimal keying results, it is crucial to adjust the camera settings appropriately, including manual iris control, disabling in-camera filters, avoiding overexposure, and utilizing features like CLASS for chromatic aberration correction.

Details​

  • Manual Iris Control: The camera’s iris should be set to manual mode to maintain consistent exposure across the entire shot. Automatic iris adjustments can lead to fluctuating light levels, which negatively impact keying accuracy.
  • Avoid Overexposure: Overexposing the cyclorama (green screen) can cause loss of saturation in the green color, which affects the quality of the key. It’s crucial to ensure that the green screen maintains its proper color without being too bright or dim.
  • Disable Camera Filters: It is recommended to turn off in-camera sharpening filters or other processing that alter the raw image. Sharpening filters, in particular, can create artifacts in the image that interfere with keying precision.
  • 3G Setup and CLASS Activation: If supported by the camera, select Level A for the 3G setup. Additionally, activating CLASS (Chromatic Aberration and Sharpness Solution) can help correct lens distortions, particularly chromatic aberration, which can affect the quality of keying.
