    I'd be interested. I get about 2 Gigs of 16 bit RGB off a 4x5 on my drum scanner and if I had a excellent tool such as this I would be happy. However, they would have to be 4800 good dpi, not like an Epson pasted on the back of a 4x5, for example. I would also build in a black and white mode... that was intelligent.

    I knew that at least a few people would be interested. The question is: how many photographers are willing to pay for such a thing?

    I am planning to prototype the one using freely available parts, and I know how to multiply the resolution and make it significantly faster.
    But, to start a company that makes them on a regular basis, it is necessary to know the potential market.

    I don't thing enough people would be interested to make a scanning back with trying to develop. A large sensor or a series of large sensors would get much more interest.

    you can't talk in the abstract. If it were $2000 very likely. If it were $5000 or more not likely.

    at $3K, i'd be interested as well.. given Kirk's conditions. The quality of the pixel's captured is important (the Betterlight has *excellent* quality). Using a MacBook Air now, the weight/size of the kit is avery manageable (not much more than taking a lot of film holders.. problem is.. if I'm shooting Betterlight, I usually bring the film holders along anyways.. )

    Q: how long it takes for your Betterlight to shoot full 3x4 (this is its size, right?) with the "shutter speed" of 1/16? Also, how many pixels do you have in the scanned image on the direction perpendicular to the sensor?

    I do think so, at least if you are targeting low volumes or individual production to order - all European makers in the field pulled out and are now catering for the digital medium format market or make process camera only backs (with even higher specifications within a very limited stationary application field). So there is a niche to fill - and with current components, prices considerably below the last generation of the 1990s designed backs by the above would be feasible.

    Re: Faster and cheaper scan back for large format.

    the sensor is 6000 pixel's wide.. will scan 8000 rows in about 33 seconds (fastest line speed is 1/240th). You can shoot at faster line times, it just doesn't decrease the scan speed any. So 1/16 will take 500 seconds to scan. From experience, I've rarely shot that slow... most of my scans are in the 30-90 second range

    This would be a great spec and outperform the standard linear scan arrays ;-) ... I assume you're scanning a 2D array since the 40 seconds at 1/16th shutter cannot be done with a linear array at the shutter times indicated. My only concern would be LCC at the proposed 5.2 micron pixel size ;-) ... of course, this can all be corrected for.

    Count me in.
