If the most popular foods of Rio de Janeiro have one thing in common, it is their informality. You can find fine restaurants in the city, but they do not set Rio apart from other places. What does set it apart, and what invariably brings its residents, known as "Cariocas," together is the unpretentious food they eat in bright, loud, crowded bars and restaurants, on busy street corners, or after a day at the beach.

Sébastien Del Grosso is a French artist and a photographer, who will allow you to enter the world of surrealism, which combines photography and hand-drawn art. His works masterfully blur the transition between the real photo and the picture. By viewing his works, we can see that Sébastien is not only a master of creating photo illusions, but also a person who tries to show his inner world through his art. His emotions, his feelings, his fears and desires are all vividly and skillfully expressed in simple strokes of a pencil. He is the continuation of his art. So much so, that he loses his identity, fearing it, but being unable to stop. (Photo by Sébastien Del Grosso)

Have you ever heard of a psychological phenomenon which lets us easily understand words, even if the order of letters is mixed up, as long as the first and last letters remain in their rightful place? Similarly, the art works of Michael Turner use only two colors to highlight the main futures of well-recognized superheroes, allowing our imagination to create the rest of the picture. The colors used in the pictures weren’t chosen at random. They perfectly reflect the key characteristics of the superheroes that they depict. For example, the picture of Flash uses red and yellow colors, which are exactly the colors of his costume. While the picture of Green Lantern is, you’ve guessed it, green and black.

Photographer Gregg Segal travelled the world to document children and the food they eat in a week.
