National Shot for SPA Nederland, a bottled water company, this series uses some fun science to shoot a series of portraits. The scientists essentially placed a diaphragm in front of a sensor to control aperture, then used a piece of glass with water-repellant coating on top of it. The coating causes droplets sitting on it to form a spherical shape. After this, an electrostatic field was applied, which varied the eccentricity of the drop (how much it resembled an ellipsoid vs a spherical shape). This, in turn, allowed the drop to be focused. The results are impressive and they certainly provide a intriguing look at a promising new way to build lenses in the future (this method is currently being developed in several places). Via
