A craze transfixing photographers lately: capturing the freezing process of soap bubbles in winter weather yields orbs with glorious, unexpected patterning. No two bubbles are the same, and footage at Fstoppers reveals as much. They also provide extra insight and include a video from photographer Benjamin Jaworskyj—revealing that photographing these bubbles is the easy part, but landing them on the right type of surface poses the most difficulty. Naturally, it has to be very cold (so do so with caution) and there can be no wind. Smooth, icy surfaces—including very cold metal—make for the ideal resting position. Learn more at Fstoppers and enjoy the images they’ve collected.
