The creative 42-year-old Mark Mawson has been taking pictures for 22 years but recently came up with his eye-catching method of creating the watery blobs. Mark, who specializes in shooting underwater scenes and people, simply takes different kinds of paint and drops them into a tank before snapping the outcome with his camera, using a strobe to light up the scene. The difference in the density of the paints creates varying shapes.
Mark needs to be constantly alert and be ready in time to press the button, because these forms quickly dissolve in water. “This is a very laborious process, but the result is worth it”, he explains. [source]
