Same exact setup as the #2 colorful bubbles. #1 was actually a failure trying to achieve #2.
Both are a paper cone light tent over a small flat dish of water, soap & food coloring. I lit the cone from the outside on 2 sides. Camera & Marco above the small dish at top opening of the cone. I think I was like 4-6" above the bubbles. Each bubble is like 1/4"-ish
I think on #1 I had waited too long and the bright colors had slid off the bubble. The colors are swirling around after u froth up the solution to make the bubbles and I take many shots. Need to take a video of the cool color movement.
