Roger, true but in this case the request was for a stringless connection to the camera. I could see it that in some cases a string might not work too well - if photographing through a window for instance? ;) Andy On Jun 3, 2013, at 7:54 PM, Eichhorn, Roger wrote: > Anyone thought of a long string attached to a weighted shutter? Pull the string to open it and release the string to close it? Maybe a few pulleys to guide the string properly, if needed. It seems to me that a lot of fancy electronics doesn't fit with the concept of a pinhole camera. > > Roger
