This is a stitched imaged made from two captures with the Rodenstock 70mm/5.6 HR-Digaron-W lens, Phase One IQ4-150 digital back (@ ISO 50), and a Cambo WRS 1250 camera, shifted left/right 15mm, producing a 230MP final image.
Note that the full resolution version isn't currently up on flickr due to a bug preventing the upload of very large images there. Currently a large (but reduced size, 100MP) version occupies a placeholder there.
