A week or so ago, Daryl Duckworth over on f295 sent me a birthday present, a biggish box containing two old craptastic cameras (one already converted to pinhole, the other begging for conversion) and a bunch of film, plus a few other goodies.

This Brownie Target Six-16 was already converted, by Daryl, but I spruced things up a bit before loading -- I cut the 616 takeup spool in half and mounted it into the core of a metal 120 spool to make a hybrid that could be unloaded in daylight (long term, I'm working on adapters that will let me swap spools like a regular 120 camera).  I made a mask for 6x10, and taped over one edge of the red window so light wouldn't spill around it and fog the film.  And then I put the camera on my tripod and stepped out before breakfast (and again after).  Careful winding on the 6x4.5 track yields six frames on a 120 roll, and after seeing the results of this roll, I altered the mask to get another 5-6 mm of frame length (as well as trimming most of the angled cut on one edge), giving a final frame of 58x110 mm (or 55x110 if I crop off the edge markings).

The big film helps a lot with the apparent sharpness of the pinhole image...



Here's the morning light angling through the trees, just before breakfast.  About 90 seconds exposure, f/225, on APX 400.



And here's the obligatory pinhole DOF shot -- the stub wall at the edge of the carport slab, the laundry room, and the little bump on the wall beyond the knobby pine branch is a grasshopper.



See, I told you that was a grasshopper -- and very much alive, just cold and soaking up some sunshine to try to warm up enough to hop properly.  Lucky for him, I wasn't doing any fishing today...
