[1] Using this information, a light stage was built by Debevec et al., consisting of Following great scientific success Debevec et al. constructed more elaborate versions of the light stage at the University of Southern California's (USC)'s Institute for Creative Technologies (ICT).

Ghosh et al. built the seventh version of the USC light stage X.

In 2014 President Barack Obama had his image and reflectance captured with the USC mobile light stage.
