Practical exercise at OUMNH: Volume
(These exercises are set in the Oxford University Museum of Natural History, but could be adapted as required.)
(For larger images and information, see the image gallery at the end of this section.)
In these studies Ruskin uses tone to create a sense of volume. The skill is to alternate light against the dark, both on the object and the background.
Materials: pencil, cream paper, grey wash.
Exercise. Take a small section of stonework and alternate the light and dark to emphasise the shadows and create volume.
