Here's a few taken with the Widelux on an overcast day. This one was taken with a Leica III (F) w/ 35mm Leitz Elmar (camera circa 1937) inside a restaurant. I love the extra speed I get. I have yet to compare it to Tri-X pushed in D-76, but most internet discussions seem to suggest that the Diafine produces a finer grain image at ISO 1250 or 1600. It does seem to be grainier to me than Tri-X shot at ISO 400, developed in D-76 1:1, but not too bad. These are scans from the negs. I like the look of the indoor shot. I'm not such a fan of the tonal range of the outdoor/low contrast shots. I thought C41 BW was low contrast; these negs were even lower contrast. Maybe the outdoor shots will look better in the darkroom. Anyway, indoors is probably where I'd be using this combo anyway. Edit: there is more info on the developer I used in the 'Darkroom' forum.
