Bev,
I use a putty like product that is sold to hang light weight objects
on the wall. You should be able to find it at a framing or hardware
store. I use a tiny bit of it positioned so it won’t show up in the
photograph. I photograph on a piece of non-glare glass. Other
surfaces may require a larger piece of putty. If the putty shows in
the image, I edit it out with image editing software, not possible if
you are shooting with film.
