For a recent expedition, I decided to equip myself with our set of Derwent Inktense pencils. These hold sticks of a watersoluble medium which produce intense colours, particularly when water is applied. Sitting on the the shoreline along Dorset’s Jurassic Coast, I ended up using sea water. It doesn’t seem to have had a particular impact on the results although I did have to brush a few grains of sand off.

What I don’t have in that set are any colours suitable for a naturalistic result so I settled for trying to capture the energy of the strong sun beating down and the surf crashing on the store.
