Abstract: Systems and methods for high performance, professional-grade photography and filmmaking in a spacecraft during space flights are provided. The systems may include an imaging studio, which is a partially enclosed volume within a spacecraft. The imaging studio may enable photography during microgravity coast phases of space flight while allowing astronauts to tend to non-photographic activities.

Imagery may also involve, among other things, a unique microgravity environment. Such imagery, without use of an imaging studio as described herein, may otherwise require artificial visual effects that may appear less realistic. Additionally, the novelty of capturing images during an actual space flight may itself be valuable.
