  "Arbres dans l'orage" (Detail) "Trees in the storm" |
Aquatint is a variation of etching aquafortis. The varnish is replaced by fine grains of resin which are sprinkled on to the metal. The plate is then heated gently to seal the resin. Soaking it in a bath of acid for a variable period of time produces the desired effect: from the lightest grey to the deepest black. Aquatint gives the drawing pointillist areas, of variable intensity, similar to wash drawing.
