@sudo Thank you, Sudo. I used a diamond shaped piece of plexiglass with a green light attached to it. The lens ball is on a champagne glass. Here is a great tutorial that demonstrates the set up. I am lazy, and have not tried using mirror lock up. I don't think it is necessary. I also do not use a paper clip to hold my lens ball as it scratches it. I use a tiny piece of putty. https://youtu.be/zRQgc-Oag4o
I am just curious, how do you capture these shots? Would love to know the process behind this
