Camera, or, Art of drawing in water colours : with instructions for sketching from nature : comprising the whole process of water-coloured drawing : familiarly exemplified in drawing, shadowing, and tinting a complete landscape, in all its progressive stages : and directions for compounding and using colours, sepia, Indian ink, bister, &c
A London drawing manual of 1823 by John Hassell, printed by J. Drury for Simpkin and Marshall, teaching amateurs to sketch and tint landscapes in watercolour step by step. Its single plate shows a finished hand-coloured landscape of a cottage on a wooded hillside beside a river, with a seated figure and a stone bridge; a designer might take its soft grey-green wash tones, layered foliage, and sepia-like shading as a model for muted, atmospheric landscape work.
