There are two major challenges, when taking images of bursting soap bubbles. One is how to light the bubble, so that its colors become visible and second is obviously to capture the right moment.
A soap bubble is made of a thin film of water, on which soap molecules gather on both sides. The vibrant colors, that bubbles are famous for, are created by the reflected light hitting the surface of the bubble. So the bubble itself has no color at all.
To make these reflection effects, that create the colors, visible, I had to place lights around the bubbles from all different sides. The reflection of the illuminated panels around the bubble (as seen in the first image) are reflected inside the bubble, creating the colors.
Now, to the second challenge, capturing the right moment. For that, you simply need high speed flashes and a LOT of patience. I did a couple of hundred shots to finally capture the moment, when soap film start to disrupt. It happens extremely quick. In most cases the bubble was already gone, when the flashes went off. But eventually one gets a sense of when the bubble bursts and the success rate of capturing the right moment starts to increase.
