    yeah me too. Not sure how much energy I would put into fiddling with building one, but if it were something that were a sure thing, more or less, I'd be all over it.

    Thanks Kirk!

    Sully, the goal is to come up with a fairly easy to replicate system. In particular, I'm trying to stay away from a design that requires expensive tools. For instance, to make my current prototype, you'd need a decent and well-aligned table saw, but it'd be fairly easy to make something similar out of alternate materials, such as threaded steel pipe, with only wrenches and a drill, at least you could for the camera support stage. Once we get a fully working prototype we can do some sample scans for people. That way you should be able to see exactly what is involved and what the results are. It certainly won't be for everyone.

    They look very clean Peter, and remarkably grain free-

    These are filthy by comparison, but they're tests of the process, and not to be seen as final output-
    from the DSLR Scanner No.7 thread-

    Details are screenshots from V750 4000dpi scans overlaid on the DSLR Stitched output, about 600kb each-
    I re-stitchsd the original; I found a few anomalies, on closer inspection-

    That's a very nice comparison, Joseph.

    Sorry, I didn't see the other thread and you hadn't received a reply in a few days. Thought I'd make a comment.

    These comparisons look really promising.

    This looks very promising indeed. I've been considering switching to dSLR since I keep having trouble with the density of my negs with my cheap HP scanner. I was surprised to find less dust with my dSLR setup than I was getting with the HP. So if I'm going to invest $1K for a new V750, I want to know if I'm better off building a rig for stitching with my dSLR. If the premise of this thread is to let the images speak for themselves, then it is a very helpful idea.

    Peter, I haven't visited this web site for awhile. Here's crop from 24000DPI DLSL scan that I made by "reverting" DeVere Enlarger:
    Original image (and number 50 outlined in red square at lower part of chrome):



    Here's 1x1 (direct from camera sensor) detail:


    You can see film artifacts. Described in this thread few years ago.

    Interesting, Victoria. Thanks for posting. I don't think I saw that thread before.
