This is 12 photos [I think it was 12 anyway!!] stitched together to form the Panorama! When the photos are stitched together, they form a curve because of the movement of the camera on the single plane of the tripod. The trick, as I have learned, is to also overlap each photo top and bottom also, so that the main subject is not going to be cropped out of the original stitch. Hope u can understand that!!! I wish I had a proper panoramic camera though..............the TIFF file of this image is approx 227Mb!!
