In the past year I have learnt quite a bit more regarding taking mosaics of macros and in processing images in Photoshop.  I saw the box containing the Owl butterfly in the loft and brought it down to redo a macromosaic of this beautiful insect.  This macromosaic is made up from 12 individual frames taken with the Canon 5D MkII and the Canon 100mm prime macro lens (with ring-flash lighting).  The final image is 8,000 x 7,000 pixels in size, in other words a 56 Megapixel image.  This is such high resolution that if you zoom in to the original image you can see individual wing scales in sharp focus!
