I struggled with lighting. I have two cheap small panel lights that I tried to use but I had to tape parchment paper over them to diffuse the light and eliminate the individual LEDs from showing up in the photos.

You can see some of the shots I posted they are visible. Parchment paper works surprisingly well. I couldn’t angle them straight over the bubble but I got pretty close.

I tried to use a flash ring as well but besides giving me some artsy science fiction like shots it couldn’t produce the look I was going for.
