It’s in the Sahel that Dicko first sourced his artistic inspiration, drawing outlines of sheep and other animals in the sand. The shadow is now a motif transpiring through his practice. Through painting, photography, video or installations, Dicko transforms the representation of forms giving life to visual phenomena, to physical and psychological events of light, uniting the two extreme values. This syncretism of seemingly polar opposites allows him to comment on issues of equality, union, maternal love and freedom.
His photographic work has received many awards. He notably won the price of Fondation Blachère in 2006 in Dakar, as well as the Francophonie price in 2007 during the Rencontres in Bamako. In 2008, in Dakar, he received the price of the Thamgidi foundation as well as the Off price from the public, supported by the European Union.
