‘My aim with this photograph was to show the amazing colours and patterns of soap bubble film with light interference.
When a bubble forms, liquid immediately begins to drain under gravity – the film becomes thinner at the top and thicker at the bottom. The draining process varies across the whole bubble – a slight change in atmospheric pressure will create a disturbance and disrupt the downward flow of liquid, which forms the swirling patterns. Due to draining and turbulence the film thickness also varies across the bubble. A particular thickness produces a particular colour and as the liquid drains away the spectacle of colours change.
Eventually black spots appear because the film has become too thin to refract any light. These spots increase in size and number until the bubble can no longer support itself and bursts.’

Post processing: Lightroom and Photoshop for minor adjustments and cleaning. ‘My work is mostly used in the science imaging industry so the final images must appear as visually close to the original subject as possible. That means I do little post-processing apart from general cleaning.’
