Typically these are little light-tight boxes with removable dark slides. You load the film into the holders in the dark and put the dark slide in place. This makes them light-tight. You then put the holder into the camera back, remove the darkslide, and expose the film. D. Heavy-duy Tripod.
View cameras tend to be large and heavy, and they require large and sturdy tripods.
New is a couple hundred dollars. Used depends on the condition and the seller's interest in getting rid of it. E. Exposure meter. Since almost all small cameras come with meters, more and more photographers manage to get through life without a hand meter. Large format cameras usually don't come with meters, so you'll either have to get a hand-held meter or use another camera's onboard meter.
