    Camera-building.

    The next step up from a large [8x10] pinhole camera would be to use a simple lens of 'bout a foot focal length coupled with a shutter [Kodak Tourist?] and a diaphragm of, say, f128. That should produce a paper negative with a decided increase in resolution while shrinking exposures down from minutes to seconds and retaining the remarkable DOF of the pinhole rig.

    Anyone gone there?

    You can look in the f295 camera building archives. It is a lot of fun and you can make nice paper negatives.

    There's quite a few threads in this very subforum about this, including one from me (http://www.apug.org/forums/forum147/129594-lf-box.html) , so yes plenty of people have gone there.

    Some of the resolution loss you're encountering with pinholes is also dependent upon the method of manufacture of the pinhole. A chemically etched pinhole can be remarkably sharp - see the Travelwide 4x5 65mm pinhole for an example. They start getting sloppy when you make the pinhole with a nail or other puncturing device. Lasers should also produce very sharp pinholes.
