Though he initially trained in illustration, Uessem devoted himself to painting, focusing on portraiture and figurative styles. He is now recognised for his large-scale photo-realistic paintings. Mixing acrylic and oil techniques in his artworks, he creates meticulously detailed paintings that look like high-resolution photographs. With the help of specific techniques, he succeeds in bringing the contrast between illusion and reality into being: The canvas is the dividing line between the spectator and the work of art is accentuated, through the blurring of specific details – a dynamic scene emerges from the static image.
