Crown Graphic Photos
One eyed cat and friend
Hand held, #5 flash bulb in on-camera Graphlite flashgun for fill.
The very first photo I took with the Graphic after I got it. Hand held.
You can even put the Graphic on tripod, though it is sacrilege.
All: 4x5 Graflex Pacemaker Crown Graphic, 135mm f4.7 Optar. Ilford FP4+.
