I have a 4x5 polaroid rangefinder monster, and I would LOVE to have a device on the camera that holds the darkslides for me (I only use double darkslides with it). If you don't know what I'm talking about, most later linhof technikas seem to have one; it's a little metal clip that you slide the darkslide into to hold it while you take your photograph. A paperclip would work...but does anyone have any intelligent solutions they can think of that I might be forgetting? Like a paperclip, but much better?
