It's amazing how wide the perspective is from my Sigma 15mm fisheye lens.

Take a look at the display cases with the flags in this photograph of the rotunda inside the Michigan State Capitol in Lansing:

While preparing to capture of picture of the inner dome, I laid down in the center of the floor. Here's that image:

The Michigan battle flags collection is housed in the state capitol. The original battle flags from the Civil War, Spanish American War and WWI were on display in the glass cases surrounding the rotunda. Now, these flags are replicas as the original flags are now kept in a special archival area for preservation. Note that the flag cases are visible in the edges of the frame. The perspective is super wide.

Last week, I was taking pictures inside Overture Hall in Madison, Wisconsin. My host was sitting a few seats to my right while I was capturing photographs of the theater from the balcony. She was surprised when I asked if she would mind moving back a bit as she was still in the frame!
