Photographer Alexander Khokhlov and makeup artist Valeriya Kutsan combine their skills to mesmerizing effect in "2D or not 2D," a surprising photography project that transforms model's faces into mind-bending optical illusions.
Via the utter time-suck that is Khokhlov's Behance page:
The key-idea of the project was to turn the models faces into the 2D images. Valeriya used different techniques of face painting so you can see a lot of variations - from sketch and graphic arts to water-colour and oil-paintings. This is a combination of interesting make-ups, studio photography experiments and careful retouching.
That combination plays craftily on our senses, toying with our perception of light and shadow, depth and proportion, to give us pause and then hold us transfixed. These face paintings represent the best kind of visual trickery – the kind that still manages to fool you, even when you're privy to its designs.
