A Gnawa traditional group performs in the city of Essaouira on December 14, 2019, to celebrate the decision of adding the Gnawa culture to UNESCO's list of Intangible Cultural Heritage of Humanity. Gnawa culture, a centuries-old Moroccan practice rooted in music, African rituals and Sufi traditions, was added to UNESCO's list of Intangible Cultural Heritage of Humanity earlier in the week. Gnawa refers to a “set of musical productions, fraternal practices and therapeutic rituals where the secular mixes with the sacred”, according to the nomination submitted by Morocco. Often dressed in colourful outfits, Gnawa musicians play the guenbri, a type of lute with three strings, accompanied by steel castanets called krakebs. (Photo by Fadel Senna/AFP Photo)

Night lovers; Hormozgan province, Iran. “In this picture, you can see the Milky Way rising on a fascinating spring night on the Persian Gulf coast. The stunning cliffs of this area make every viewer imagine and even talk to them! The light pollution from a faraway city was quite strong, so it was a challenging post-processing process. I’m a nightscaper who tries to achieve an artistic look in my images, and in this image, I tried to convey and capture the magic of this location”.

Terence Chang's (aka exxonvaldez) long exposure photographs, capturing only streaks of light as airplanes arrive and depart from the San Francisco airport, certainly are stunning. There's just something so magical about seeing the various patterns created in the sky, even over a relatively short amount of time.

French Levalet is back in the streets of Paris with this new piece entitled ‘Le marchand de sable’/’The Sandman’, a rather literal interpretation of the mythical character in central and northern European folklore who brings good dreams by sprinkling magical sand onto the eyes of children while they sleep at night. Funny and smart as usual.
