The Ice Castles in this gallery represent the St. Paul Winter Carnival Castles from 1987, 1992 and 2004. The color of the Ice Castle would change every 15 sec. The exposure time for the images was 15 sec. The images that have multi colors resulted from starting the exposure during the second half of one color and continuing the exposure into the next color. All images high res scans from the original 35mm negs and colors are as shot and NOT altered in any way.
