"Frankenstein's Dream" (From my book "Curiopticals": ) When you see the picture close-up, the fine details dominate (Frankenstein), but when you observe it from a distance, the larger, more blurred tones become more
coherent and, in this case, a beautiful diva appears! (fig. A)
A lot of artists used similar optical processes to create ambiguous artworks, such as Salvador Dalí’s intriguing painting “Gala Contemplating the Mediterranean Sea Which at Twenty Meters Becomes the Portrait of Abraham Lincoln” (1976).
You can make such amazing cryptic optical illusions too, with Photoshop, by blending together two faces in one hybrid image. You just need to smooth (high-pass) one image, and sharpen (low-pass) the other one. This method can be applied to other kinds of subjects, but face swapping seems especially amazing...
Posters and t-shirts featuring this image are available from my online store:
