Back in the studio, Gadenne usually modifies his pictures quite a lot before painting them, changing the light, colors, and composition. However, he found that the photographs he took underwater already had the uncanny aspect he longs for in his work. A sense of eerie, blurred, and bluish backgrounds helped him create a strong sense of depth in this series of landscapes. This oil painting series was challenging nonetheless, due to the new color palette he had to work with and the infinite level of details in the coral structures, which he had to simplify one way or another. He wanted to render the density of the water and its surreal colors at the same time.
This exhibition also features a series of oil pastel drawings, which Gadenne describes as a great balance between the underwater coloring pencils drawings he did on-site and his oil painting practice in the studio. It allowed him a more spontaneous approach to rendering the different colors and textures of this immersed world, playing with contrasts of hues and saturations and looking for interesting compositions in the chaotic-looking rocks and corals one can find on a reef.
