The atmosphere creates a sense of distance because tonal values lighten the further away something is. Detail is less clear and focus is reduced by the amount of air that we view the landscape through. … Using tonal drawing media such as charcoal, soft graphite, conte crayon, soft pastel, oil pastel or watercolour make several tonal studies that analyse receding features of the landscape from foreground to middle and far distance. … You can work in colour or monochrome at this stage.
Initially I had some difficulty finding a suitable viewpoint for this exercise. However at the back of the Lowry there is a sculpture called Where the Wild Things Were, which is based on the savannah grasslands of Africa, from where many products were imported into the UK through the Salford Docks. With this in the foreground, the new footbridge in the middle distance and old warehouses in the far distance, I felt this was a suitable view. I did two versions of the scene.
Firstly I drew in graphite pencil, using 2H for the distant buildings, HB for the bridge and 3B for the sculpture in the foreground.
For the second version, I used various dilutions of Indian ink, with the distant warehouses in the palest, most dilute mixes and the foreground sculpture in the strongest. I tried to add some more aerial perspective in the sky with clouds but this was not very successful as they look more like barrage balloons.
