I am priviledged to take Architectual photos of projects for Schmidt Associates (where I work). I love taking photos of Auditoriums. Not sure exactly why but they always turn out to be some of my favorite shots; somehow they tend to look better than I expected when composing the photos.
Here are a couple more examples.
New Plainfield High School Auditorium
ISU – Auditorium Addition and Renovation at Bayh College of Education building
