A Dutch scientist began experimenting with substances called silver salts and in a pamphlet published in 1614, he stated that when powdered silver nitrate is exposed to the sun, "it turns as black as ink".

In 1558, He refined the camera obscura by incorporating additional lenses and curved mirrors.

He created the first permanent photograph using a process he called heliography

The first widely accepted form of photography, producing detailed images without the use of negatives. Each photograph was unique, as the process did not allow for multiple prints from a single negative.

When was the flashbulb invented, making it possible for a portable light source to enable the taking of many evidence photographs?

When was the International Association for Identification formed? It has evolved into the oldest and largest forensic science organization in the world.

It was the first to offer instant photography, where a photograph could be taken, developed, and printed in about one minute. This was achieved through the use of instant film, which developed itself through a chemical process within the camera.

In 1880, Abney introduced as a photographic developer.

He is indeed credited with creating the first color photograph. In 1861, he demonstrated the process using an additive color technique.

A hungarian mathematician and physicist, made significant contributions to early photography by developing advanced lenses. These lenses greatly improved the quality and efficiency of photographic processes.

He invented the calotype, a silver chloride-coated light sensitive paper that was fixed with strong salt solution

He introdauced a diaphragm, which helped control the amount of light entering the camera obscura. This addition improved image clarity and contrast.

It is an optical device that has been used for centuries to explore the principles of image formation. It means "dark chamber in Latin, reflecting its basic structure and function.

An English Botanist, she is considered to be the first female photographer.

He discovered that sunlight darkens a mixture of chalk (calcium carbonate) and silver nitrate.
