    1MP distorted images? Bah.... what you need is something like this - a 122 megapixel flatbed scanner back for a large format camera:

    http://www.cs.ubc.ca/~szwang/Research/ScanCam/scancam.html

    That's right, 122 megapixels.

    If you read the actual master's thesis written by that guy, the biggest problems are getting a scanner that is compatible with a cameras optics (you have to remove a little lens assembly over the scanner head to get it to work), aligning the scanner with the image plane, and most difficult: a TON of image processing to remove scanner artefacts and get a calibrated image. Oh yeah, you also need incredibly intense light, and three exposures - for the red, green, and blue channels. Because they only tested it in studio conditions with abnormally bright lighting I'm not sure how useful it would be for something like landscapes.. still it's a cool idea, and not very expensive, especially if you already have a large format setup and just need to build the scanner back.

    I haven't read either site, just flicked, but it looks interesting. I have used the scanner as a camera. But by placing objects on it. No, not scanning.

    Of course with plain, old large format film scanned at 4000 dpi you can get a 320 mp file from 4x5, and a 1280 mp from 8x10. And no need to tote a car battery (or a very long extension cord) if you are shooting outside the studio. :wink:
