I am interested in taking self portraits with a LF (4x5) camera. I have read other threads on this topic but am still a bit confused. If I were to purchase an autoknips II and attach it onto a cable release which can do long exposure, would this work? Many of images will be created in low light situations and as such exposure will need to be longer than a second. Can anyone give me a direction (phone number, website) to find cable releases which have exposure time built into them? I have heard of prontor, but cannot find their website nor any information other than in forums and on ebay, and they do not have what I am looking for.
Thank you for your advice,
