I've just moved to a new home and I'm starting to set up my camera collection for display. I have a bookshelf where I am going to display my camera collection in my living room. It's not going to be just for display. I will put several cameras on the shelf that I will use from time to time. Some will be "shooters," some will be "keepers" and the rest will be just for display. "Shooters" will be taken out to be used regularly. "Keepers" will be be used only occasionally. The rest will be for display only. Essentially, this display shelf is going to be like a gun rack... only for cameras. I have several cameras with bellows, either rangefinders or various other folding types. There is a Speed Graphic and some other things like that. The question whether I should store or display the cameras with bellows open or closed? Will leaving them open all the time damage them? (e.g. the leather cracks?) Will leaving them closed do something similar? Does it even really matter so long as one is careful opening and closing the cameras? To use the "gun rack" analogy, some people store their guns with the actions open for safety reasons but some store them with the actions closed to keep them from getting damaged or dirty. I think I am going with the "It doesn't matter so long as you are careful" option but I just wanted to check in and see what others thought.
