- Silver halide photography depends on grains, which are either darkened or not, according to whether photons have hit them. A grain can only be black (reduced to silver) or transparent, so this is an on-off way of building an image. Both film and silicon sensors make use of the photoelectric effect, whereby a photon incident on an atom releases ...

- The light sensitive silver halides, silver chloride, silver bromide and silver iodide, are used to make photographic film and photographic paper. ... (aq), potassium bromide, KBr(aq) and potassium iodide, KI(aq), solutions are all LOW HAZARD. Solutions of the sodium salts can be used in place of the potassium salts. See CLEAPSS Hazcard HC047b ...

- Many salts are halides; the hal-syllable in halide and halite reflects this correlation. All Group 1 metals form halides that are white solids at room temperature. [citation needed] A halide ion is a halogen atom bearing a negative charge. ... Silver halides are used in photographic films and papers. When the film is developed, ...

- The activators are halide salts, generally chlorides and fluorides, that react with the metallic component of the pack to form metal halides having high vapor pressures.For aluminide coatings utilizing an ammonium chloride activator, the reactions involved in the formation of the coating composition are summarized in Fig. 6.5.The activator eventually creates AlCl vapor.
Silver halide - Wikipedia

- Silver-based salt used in photographic film and traditional photographic paper. A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver (Ag) and one of the halogens. In particular, bromine (Br), chlorine (Cl), iodine (I) and fluorine (F) may each combine with silver to produce silver bromide ...

- To understand the fundamental chemistry of silver-based photography, we must look at the photochemistry of silver salts. A typical photographic film contains tiny crystals of very slightly soluble silver halide salts such as silver bromide (AgBr) commonly referred to as "grains." The grains are suspended in a gelatin matrix and the resulting ...
Which of the following salts are used in photography?
- https://testbook.com/question-answer/which-of-the-following-salts-are-used-in-photograp--607e9336d0fbe4be37e97cc8
- Explanation: Silver halides are used in black and white photography. A photographic film is coated with silver halide. When light falls on the surface, the exposed part of the film is darkened from which photograph is developed. That’s why it is used in photography. The salts are reduced to the metal form when light falls on them.

- Answer (1 of 3): That is highly depend on particular chemistry. But, if you are talking about salt print, then ordinary salt (kosher one if you are in the USA) and soak watercolor paper for a while, once you dry, you can apply silver nitrate solutions to paper to create light sensitive paper bec...
Salt printing: Exposing the print
- https://www.alternativephotography.com/salt-printing-exposing-the-print/
- The salt print requires ultraviolet (UV) light to form an image. The sun, or alternatives such as lamps or tubes emitting UV light can be used. The ligh sources essential for printing-out processes are a million times stronger than those for developed-out processes.[40] Photographic enlargers cannot produce enough light for printing-out processes.
