This HDR image of the cathedral in Canterbury, England is a composite of two separate photos taken from roughly the same angle. My first photo had underexposed the foreground arch, so I took another one with flash, but this slightly overexposed the rest of the image (especially the sky). I hadn’t originally taken the photos with the intention of creating an HDR image so they didn’t exactly match, but I thought they were close enough in composition that merging them was worth a shot. The end result turned out better than either photo had looked on its own.
