Photography
Silver-based photography is based on light striking
sensitive silver-halide crystals suspended on a film. Through use of chemical ‘developers’ the differences in
light intensity form negative images which can then be processed into paper pictures by using silver-imbedded
paper. Approximately 5,000 color photographs can be taken using one ounce of silver.

Because of the growth of digital photography, the use of
silver-based imaging by consumers has been steadily
dropping for almost a decade. Although many had predicted that consumers would turn digital images into paper –
using silver halide products – many picture- takers either keep their images in digital form or use low-cost,
ink-jet printers.

Nonetheless, because of its extreme accuracy and cost
effectiveness, silver-halide films are still chosen for some applications. For example, medical X-Ray technicians, especially those in
developing countries, often prefer silver-based pictures because of their low cost and high accuracy. In
addition, many motion picture makers still prefer silver- halide film over digital, because of its low cost,
excellent resolution and true color properties.
