“ Most young amateurs have an idea that it requires a great deal of skill to make lantern slides, but any one who can make a good negative can soon learn how to make a good lantern slide. The simplest way is by contact-printing. Select a negative free from spots, scratches, or pinholes. It must have fine detail in the shadows, and no harsh contrasts of light and shade. The regulation size of a lantern slide is 31⁄2 by 4, so choose a negative which will still make a good picture if all but the portion included in these dimensions is blocked out. ”
