In 1835 Ruskin received a series of around eight or nine lessons from Fielding who taught him:
to work colour smoothly in successive tints, to shade cobalt though pink madder into yellow ochre for skies, to use a broken scraggy touch for the tops of mountains, to represent calm lakes by broad strips of shade with lines of light between them... to produce dark clouds and rain with twelve or twenty successive washes, and to crumble burnt umber with a dry brush for foliage and foreground.
