These are photographs of the 1915 San Francisco Pan Pacific Exhibition as reconstructed on the virtual world of Blue Mars. IDIA Lab is a part of Ball State University, in Indiana U.S.A. did this reconstruction. They have some of the best virtual world constructions on there are of Blue Mars anywhere.
I did a You Tube video of my avatar Roger touring IDIA labs on the virtual ride IDIA labs built to tour all their constructions.
I took these photographs at Sunset on Blue Mars with little processing other than a filter to bring out details.
