I have to take pictures of mineral specimens without hands in the picture. I looked at the prices of acrylic stands and would prefer to try make my own or use existing materials. At this stage, I am eyeing bird spikes to use as material. I will welcome any thoughts.

HI PIERRE,
You can see from my specimen pictures that I have a lot of full cabinet size examples. Many don't support themselves at a desired viewing angle when on their display shelves so I have taken to recycling clear juice containers, milk containers, or other food containers. You can cut them with a shears or heavy duty scissors to make "custom" mounts with a low cut front for viewing and a higher back for support. All angles are possible so most look quite good for costing next to nothing. Here is an example, viewed both from the front and side, with a ruler for scale. Originally, the mount was a clear plastic juice container.
This method probably would work just as well for taking pictures of larger specimens without much intrusion into the photos. Hope this is of some help. BOB

Hi Pierre,
Ideally, you should not see any kind of support holding the specimen at the proper viewing angle while photographing it. Bird spikes would probably work, but they would have to be anchored in some sort of base (wood?). As long as the base and the spikes weren't visible they would be alright I suppose.
I use a variety of high density styrofoam wedges to support the mineral during photo sessions. Unless your specimens are very large and heavy, these work fine and can be easily cut to proper angle and size with a utility knife. Occasionally a couple of wedges are needed to support the piece.
It is important to note that the foam is not the same material that is used for food containers and drinking cups. That material is too thin and soft and would degrade too quickly although it would probably work okay in a pinch. The stuff I use is a 1" thick extruded foam board that is used in the construction industry. A small sheet is inexpensive and will make enough supports to last a lifetime.
Good luck,
Michael

Hi Bob, Thank you very much for the photos and ideas. I was thinking about cutting strips from some plastic containers. Your's is a great idea and I will look to see what I can use.
Hi Michael, using the dense white foam, is a great idea. White will work well with a white background, but I suppose you will have to paint the foam black for black background and use the base, on which the specimen sits, also from the same material. Using bird spikes: I plan to drill holes in a thicker piece of clear plastic and gluing, or plastic welding, them in these holes.
Of course I am a great fan of using hands for most photography of specimens, with the exception of small and large specimens. I have damaged a number of specimens, attempting other methods. Hands are safe and quick and people get an idea of the actual size of the specimen. Nevertheless, when in Rome, do as Rome does:-)

I was looking at different solutions to my photography problem, even praying for a solution, when i remembered an article by Paul S 'a DIY Ball Table'
https://www.mineral-forum.com/message-board/viewtopic.php?t=1150
I have some thick ceiling foam and will experiment with simple squares with different sized holes in them. That should help. I will paint the foam black that I intend to use with black backgrounds. Hopefully that will help solving my problem.
Any further ideas are welcome.

Most of my pictures are made with the specimen on the back of my black bible. I move it and myself around and take lots of pictures and find what works best. Then do another round until I get the shot I want. Sometimes I hold the crystal on a cloth in my hand with the same procedure. This doesn't meet the highest standards of aesthetics, but it demonstrates the features I hope to highlight.
My problem comes when making a display. Then stands are necessary to hold the specimen in the right orientation. I've used pieces of clear acrylic rods held on with hot glue, strategic uses of putty with harder pebbles, clear mineral boxes ground into the right shape like the bottles in the previous post, and finally painted wood blocks with the right shaped holes carved out with a dremmel tool.
Since my specimens aren't so aesthetic and expensive, I've been satisfied with these.

I have an idea that these clear acrylic rings will do the trick just fine.
