When the sky of a landscape negative is thin, dirty, or uneven, it is better to render it entirely opaque, and print clouds in the proof by a second operation. Go round the edge of all the subject part with a fine brush and any kind of yellow paint. Take great care to preserve the outline of the picture part, and afterward go over the whole sky with "opaque," taking care that no part is left uncovered. It may be applied on both sides if necessary. A useful way to improve a landscape negative is to paste on the back a thin sheet of tissue paper, and then, holding the negative up against the light, going over it where necessary with a soft black pencil and a crayon stump. Instead of the tissue paper, the appearance of ground glass may be imparted to the back by an application of "ground glass varnish," a formula for preparing which is given in the Appendix. On the surface thus prepared any work may easily be put with the pencil. After the amateur acquires a little skill and experience he may try his hand at painting in sheep on a lawn, swans on lakes, a boat on a river, or essay flights of genius in other or similar directions. It will have been understood that clouds may easily be painted in upon a landscape negative when the sky is not quite opaque, but thin enough to print with a tint. CHAPTER XII.

For the photographer who can devote several consecutive hours during the day to the production of lantern slides, or wbo manufactures them on a large scale, the wet coll...
