Adjustable Platform for coin photography

Post by SP67 » Thu Apr 01, 2021 2:36 pm

Here is a tip-tilt platform I recently developed. Nothing very complicated, but it helps a lot for taking pictures of your favorite coin errors.

The platform allows to tilt your coin in any angle over +/- 45 degrees.

You can now optimize the rendering of the feature you want to highlight.

Cost: 16$ including shipping in Canada.

The set includes 2 inserts to accommodate various coin sizes.

Just send me a private message if you are interested to get a set or need more information.

You can find some discussion here on the French side of Coinsandcanada.

Most of you know that it's not always easy to put in evidence the beauty of our coins or specific errors. We can obviously play around with the projection angle of the light source, but in many cases, this is not enough.
The additional trick is to adjust the coin's viewing angle (tilt) with the camera. Unfortunately, most of the time our setup makes it difficult to tilt the coin to large angles, unless you tweak temporary supports that may not be stable or ergonomic.

This new platform is based on a hemisphere sitting over a 3-point base. This configuration allows the angle of the sphere to be adjusted in all directions. The flat side of the hemisphere contains a series of rings adjusted to Canadian coin sizes, from 1 cent to 1 $ silver. A raised border keeps the coin safely in place. A set of inserts allow various coins size.

This small tip-tilt base is easy to use and very practical. I'm using it almost every day now, in combination with my Celestron USB microscope.

This picture shows the rendering improvment. The left side is based on conventional lighning from the microscope. The clash is barely seen. The middle picture is taken with an external light. Some improvment, but not the best. The right image has been optimize by tilting the coin to get the best contrast on the clash.
