It resembles the lens opening, mid-snapshot, as the camera mechanisms are regulating the amount of light let in. This is what determines whether an image is dark or light.
This vase of Clear crystal, however, is all light, heightened all the more as the light refracts beautifully off the bowl’s swirled pleating. Whether or not you happen to be a photography aficionado, this vase has an exciting sense of gathering momentum. The visual effect is that of a whirlpool of luminosity, a rush of energy anchored in Clear crystal. The wide neck makes it perfect for displaying a large bouquet.
