One of the figures in a group of two in a photograph is sometimes required to be removed. It is clone as follows. Mix up a neutral tint with ivorylblack, ultramarine, crimson lake, and sepia, and add plenty of gum - that is, gum arabic soaked in warm water till it dissolves. Stipple out all the light parts, such as the hands, the face, the lights on the dress, etc., till it matches the middle tints of the background. Then treat the shadows with Chinese white in a like manner, till the two match as nearly as possible. All this should be done by making fine dots close together with the point of the brush. The paint should not be too wet, but wet enough to work easily. Of course, if the photograph is a silver print, the figure could be painted right out by brushing it over with a strong solution of cyanide of potassium or persulphate of ammonia, but the former is the neater plan, and is more under control. Moreover, should it be desired at anytime to restore the figure, the paint can be washed off again.
