Raid, these are not stitched together they are full frame from the Horizon Russian swing-lens panoramic camera. One of the disadvantages of the swing lens is that if the camera is not level then you get a curved horizon line. These are very interesting photos, especially as Frank says, the ones of the wealthy community, but I wish the horizon did not have to be always centered in the picture. Tough choice because if the horizon is high or low in the frame, it gets really distorted, that's just the way the optics work in this type of camera.
