Early in this century, a number of photographers dedicated themselves to demonstrating and exploring the artistic possibilities of the medium. One of the best was Edward Weston. These salts turn black when they're exposed to light. When light is projected through the negative onto silver-emulsion paper, the darks and lights are reversed again to create the positive image. A great deal of skill is often involved in controlling the amount of light that is projected through different areas.

Hunting scenes featuring animals have been enormously popular among American collectors for more than 150 years. This is a particularly good example, with a real sense of electricity in the postures and expressions of the three dogs, who dominate the composition. The viewer can easily imagine himself in the hunting scene, feeling the excitement of the beasts. The central panel depicts a snow lion, one that might be found in the mountainous regions of Tibet. Both the lions and the mythical dragons probably send a message regarding the power of the owner or some symbol relating to his family.
