I was right. My photo was used in the “Luminescence of Gems“, presented by Dr. Emmanuel Fritsch.
To recap, as reported in my earlier post, at one point in the presentation, I recognised a photo that was being used to demonstrate a particular feature, even though it was shown sideways. It is one of mine! Unfortunately, the attribution given was simply Mindat, which is insufficient. Mindat don’t own the copyright. The photographer does. I would have preferred to see my name against it. I am sure others would feel the same way.
Anyway, the video is now available here.
