This photo was taken in Sao Tiago Hotel, Macau. It is composed of two shots. I do not recall the exposure settings which were the same for both shots. After I took the first shot, I panned 3/4 frame. Then take the second shot. I overlapped the two about 1/4 of frame, so a photo processing software can match up the two photos. Avoid wide angle range between 28mm and 35mm, the edge distortion makes the panorama look weird. Many photo processing software can stitch photos. This particular photo was stitched by a software came with my old Canon printer.
