These are samples of "Proof" level scans.  The proof scans are captured with a high resolution 24MP digital camera on a fixed camera-stand.  All of the images are then processed with Adobe Photoshop for automated color and exposure corrections.  Additional manual corrections are possible for all of the images.  Click on a photo on left to see that image.  Click on the right-side image to bring up a full screen view.  Image 9 shows a comparison of different scans - the printed 4x6 scan (09_PS), the original "Proof" scan (09_NC), additional edits to the Proof (09_NCE), and a detailed scan on a film scanner (09-NSE).
