I had seen some macro shots of borosilicate marbles and they were fabulous. This was my first attempt. I would love to have more of these marbles but they are quite pricey...so just sticking with the one for now. I need to practice more but wanted to post this first shot. This is quite a challenge as the marble is round as well as trying to figure out what point to focus on. I did use in-camera focus stacking which I think helped some.
