- Title: Jointly Optimizing Color Rendition and In-Camera Backgrounds in an RGB
Virtual Production Stage
- Abstract summary: LED panels used in virtual production systems produce problematic color shifts when used as lighting due to their peaky spectral output from narrow-band red, green, and blue LEDs.
We present an improved color calibration process for virtual production stages which ameliorates this color rendition problem while also passing through accurate in-camera background colors.

- Abstract: While the LED panels used in virtual production systems can display vibrant
imagery with a wide color gamut, they produce problematic color shifts when
used as lighting due to their peaky spectral output from narrow-band red,
green, and blue LEDs. In this work, we present an improved color calibration
process for virtual production stages which ameliorates this color rendition
problem while also passing through accurate in-camera background colors. We do
this by optimizing linear color correction transformations for 1) the LED panel
pixels visible in the field of view of the camera, 2) the pixels outside the
field of view of the camera illuminating the subjects, and, as a post-process,
3) the pixel values recorded by the camera. The result is that footage shot in
an RGB LED panel virtual production stage can exhibit more accurate skin tones
and costume colors while still reproducing the desired colors of the in-camera
background.
