I had just left my room at the historic Mission Inn and Spa in Riverside, California when I saw the sunrise looked like it was going to be spectacular. Althought it was still quite dark, the horizon was turning more orange by the minute. I went back to my room, grabbed my camera, tripod, expodisc white balancer, and off camera shutter release. I decided to shoot an 4 image wide x 3 image high HDR panorama. Each photo consisted of 10 exposures between -5ev and +5ev for a total of 120 individual exposures. The final panorama was more than 20,000 pixels wide and the color corrected file tipped the scales at 1.4GB in size. After taking this shot, I quietly walked around the property taking more photos until one of the security guards stopped me, asking if I was a registered guest. I produced my room key and gave him my name. He radioed the front desk. Once they confirmed my identity, I was allowed to continue taking photos so long as I didn't disturb any of the other guests.
