I'm a big fan of Surrealism. The whole concept of trying to express the subconscious and dreams through art is very fascinating to me. Some of the paintings by Salvador Dali and Max Ernst are really intriguing. Every time you look, you have a different interpretation of what they meant to express. And these days we've been seeing a lot of that in the digital art world; what they call Neosurrealism.
Neosurrealism is a combined imagery of dreams, fantasies, and subconscious mind visions in fine art painting, digital art graphic, and photography. In the mid 1980s, modern computer technologies brought a large amount of additional depicting power to contemporary artists not possible by hand. The arrival of desktop publishing and the introduction of software applications introduced a generation of artists to computer image manipulation and 3D image creation that had previously been unachievable. There are thousands of artists, digital and traditional fine art media, who create neo-surrealistic, surreal fantasy, and fantasy realism artworks comparable to Neosurrealism.
Below you can see amazing examples. Enjoy ;)
