Silver is used in film media because it tarnishes better than other materials.
Tarnish is the process of oxidation, where a metal turns from some some shiny color to a darker non-shiny color.
Three Examples of Tarnish:
- Gold: Starts a bright shiny gold color and tarnishes to a slightly darker dull gold color
- Copper: Starts a bright shiny orange-gold color and tarnishes to a green patina color
- Silver: Starts a bright almost white color and tarnishes to a very dark grey, almost black color
Silver provides the best tonal range, from light to dark. It can capture light from pure white to pure black (or very close).
Additionally, silver tarnishes very consistently. This provides a smooth transition from light to dark on film.

Silver Halide Silver iodide
What is a silver-lined umbrella in photography?
A silver-lined umbrella is used to diffuse light from a flash that is pointed into the umbrella and therefore illuminates the subject with light from a large surface (the silver lining).
What metal is used to make jewelry?
Prior to the advent of digital imaging during the 1980s, most conventional photography was silver-based, although historically other metals, most notably Platinum were also used to produce permanent printed images. Silver-based photography had its beginnings with the Daguerreotype process in 1839, which produced a one-of-a-kind image on a copper plate. Silver based images remained the primary technology for all subsequent pre-digital photography, including the mid-19th Century Collodion Wet Plate process and the modern flexible substrate films of the 20th Century. In the color negative film process, developed silver is replaced with dyes in layers.
Does silver have a reaction?
Yes - silver does react and that is why there are quite a few compounds of silver. It is used in photography for example.
What mineral is used for photography?
it is silver
Is silver bromide used in photography?
Yes
Which Salt is used in photography?
Silver nitrate.
Is the element silver used in photography?
It is widely used in standard film-based (pre-digital) Photography.
Is the element silver widely used in photography?
It is widely used in standard film-based (pre-digital) photography.
What property of ionic compounds explains why silver halides can be used in photography?
Silver halides absorb light to form elemental silver. This is the basis for the photographic film. This is an unusual reaction and is certainly not common to all ionic compounds. Silver halides are also unusually insoluble, again not a common property of ionic compounds. In fact silver halides have quite a lot of covalent character! I am sure teacher has something in mind but its certainly not in mine.
When was silver bromide first used in photography?
1840
What element is used in photography and as an antiseptic?
Iodine ******** And silver.
How is iodine used in photography?
it is used in the compound silver iodide and it reflects the light. it is essentially the basis of black and white photography.
What is a compound used in photography which darkens when exposed to light?
Silver Halide Silver iodide
Which compound that darkens in light used in photography?
Silver Iodine
