Twice now I have found myself without cable release when shooting the Zeiss Ikonta. Both times I resorted to folding stems of dry grass into a shape suited to pressing the shutter lever on the front of the lens. In one case the tripod was too spindly for the double duty of holding camera still and steady. So I had motion blur.
Note to self. This defeats the "double-exposure-prevention" interlock.
My little Welti Weltix presents me with the same problem. I don't use it often enough to recall the unlock/advance/cock/release shooting sequence until I have wasted a frame (or two). It's not until the shutter refuses to fire that I realize that I've got the order wrong (again. ). A cable release bypasses the idiot proof mechanics of the camera and allows me to fire the shutter.

Ansel Adams had the Zone System... I'm working on the points system. First I points it here, and then I points it there...
