Si (14 Silicon) : "Because silicon is an important element in high-technology semiconductor devices, many places in the world bear its name. For example, Santa Clara Valley in California acquired the nickname Silicon Valley since the element is the base material used in the semiconductor industry located there." (en.wikipedia.org/wiki/Silicon)

Ag (47 Silver) : "Its compounds are used in photographic film and X-rays. Dilute silver nitrate solutions and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages and wound-dressings, catheters and other medical instruments." (en.wikipedia.org/wiki/Silver)

Br (35 Bromine) : "Bromine compounds are still used in well drilling fluids, in photographic film, and as an intermediate in the manufacture of organic chemicals." (en.wikipedia.org/wiki/Bromine)

The photographic technique involves the following steps:

1) Preparation of sensitive plate or film
It is an emulsion of AgBr in gelatin uniformly coated on a glass plate or a celluloid sheet (film) in a dark room.The process is done in dark because AgBr is highly light sensitive.

2) Exposure
The sensitive plate or film is mounted on a camera and exposed for a few seconds to the image of a properly focused object. An invisible change occurs in that part of the emulsion on which light falls.The chemical reaction is that light reduces AgBr to Ag.
Br- + photon -------> electron + Br
Ag+ + electron -------> Ag
An image of the object is formed on the film which is not visible and therefore called latent image.
