For “Solo: A Star Wars Story” the filmmakers had an unprecedented amount of control over the environment using projection technology and back-lighting.
Sweetwater installed a large projection setup around the Millennium Falcon cockpit, enabling the cameras to create a truly immersive environment.
The ultimate goal of the projection belnd was to capture crisp, realistic, high-resolution lighting and reflections in camera, that could be captured in 6K.
These projections gave the actors an actual environment to work in, creating a greater connection between the actors and their characters.
