Excerpt from The Advance of Photography: Its History and Modern Applications Nearly forty years have now elapsed since the first edition of Vogel's Chemistry of Light and Photography was issued, and no revision has been made of that work since 1883. During the last thirty years the science of photography has developed with very rapid strides. The perfection of the dry plate, the introduction of orthochromatic photography, and the scientific investigation of the many problems confronting the practical photographer have been landmarks in that progress.
