Right now, I feel like what I've done is in the wrong part of the pinhole area. The few things I've produced so far strike me as being blurry lens-type shots. There's really no point to them. Then again, they're the result of wandering around the yard for half an hour the day the pinhole body cap arrived. The first two photos at <http://www.dd-b.net/dd-b/SnapshotAlbum/data/2003/08260-Weird%20Tech/> are among my more presentable S2 pinhole images. What I *want* to play with is 4x5 studio pinhole macro. Using studio strobes on a tiny subject should keep the exposure time down to finite periods, and doing sharp macro work with infinite depth of field would be a *very* different look. I dunno how sharp 4x5 pinhole actually is really, though (assuming a good choice of pinhole size for the focal length of course). -- David Dyer-Bennet, <mailto:dd-b@xxxxxxxx>, <http://www.dd-b.net/dd-b/> RKBA: <http://noguns-nomoney.com> <http://www.dd-b.net/carry/> Photos: <dd-b.lighthunters.net> Snapshots: <www.dd-b.net/dd-b/SnapshotAlbum/> Dragaera/Steven Brust: <http://dragaera.info/>
