1025. Important

Important. For all lantern-slide work, the strongest and most brilliant colors are not only desirable, but necessary, and it is important that the very best make of colors be secured, for the strong light of the lantern will fade them after they have been in use for some time, if the colors are not sufficiently pure to withstand the action of the light.

1026. Be very careful to keep the dust off the slide while it is moist, and when colored, place it in a negative rack, or, lay it film side down to dry, one end slightly elevated so that nothing will touch the film.

1027. A white card, laid back of the slide while coloring, will show small details perfectly.

1028. Follow these directions as carefully as possible. It is best to experiment with half a dozen slides, which are not particularly valuable, before venturing upon something of more worth.
