A photograph is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor, such as a CCD or a CMOS chip. Most photographs are now created using a smartphone/camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see. The process and practice of creating such images is called photography.
The collodion process is an early photographic process. The collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed, and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field. Collodion is normally used in its wet form, but it can also be used in dry form, at the cost of greatly increased exposure time. The increased exposure time made the dry form unsuitable for the usual portraiture work of most professional photographers of the 19th century. The use of the dry form was therefore mostly confined to landscape photography and other special applications where minutes-long exposure times were tolerable.
Photographic plates preceded photographic film as a capture medium in photography, and were still used in some communities up until the late 20th century. The light-sensitive emulsion of silver salts was coated on a glass plate, typically thinner than common window glass.
Panoramic photography is a technique of photography, using specialized equipment or software, that captures images with horizontally elongated fields of view. It is sometimes known as wide format photography. The term has also been applied to a photograph that is cropped to a relatively wide aspect ratio, like the familiar letterbox format in wide-screen video.
The albumen print, also called albumen silver print, was published in January 1847 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the start of the 20th century, with a peak in the 1860–90 period. During the mid-19th century, the carte de visite became one of the more popular uses of the albumen method. In the 19th century, E. & H. T. Anthony & Company were the largest makers and distributors of albumen photographic prints and paper in the United States.

Richard Daintree CMG was a pioneering Australian geologist and photographer. In particular, Daintree was the first Government geologist for North Queensland discovering gold fields and coal seams for future exploitation. Daintree was a pioneer in the use of photography during field trips and his photographs formed the basis of Queensland's contribution to the Exhibition of Arts and Industry in 1871. Following the success of the display, he was appointed as Queensland's Agent-General in London in 1872 but was forced to resign in 1876 due to ill-health and malpractice by some of his staff although not Daintree himself. A number of features in North Queensland have been named after Daintree including the town of Daintree, Queensland, the Daintree National Park, the Daintree River, the Daintree Rainforest which has been nominated for the World Heritage List and the Daintree Reef.

The conservation and restoration of photographs is the study of the physical care and treatment of photographic materials. It covers both efforts undertaken by photograph conservators, librarians, archivists, and museum curators who manage photograph collections at a variety of cultural heritage institutions, as well as steps taken to preserve collections of personal and family photographs. It is an umbrella term that includes both preventative preservation activities such as environmental control and conservation techniques that involve treating individual items. Both preservation and conservation require an in-depth understanding of how photographs are made, and the causes and prevention of deterioration. Conservator-restorers use this knowledge to treat photographic materials, stabilizing them from further deterioration, and sometimes restoring them for aesthetic purposes.
Bernhardt Otto Holtermann was a successful gold miner, businessman, politician and photographer in Australia. Perhaps his greatest claim to fame is his association with the Holtermann Nugget, the largest gold specimen ever found, 59 inches (1.5 m) long, weighing 630 pounds (290 kg) and with an estimated gold content of 3,000 troy ounces (93 kg), found at Hill End, near Bathurst, New South Wales. This gave him the wealth to build a mansion in North Sydney, which is now one of the boarding houses at Sydney Church of England Grammar School.
New South Wales experienced the first gold rush in Australia, a period generally accepted to lie between 1851 and 1880. This period in the history of New South Wales resulted in a rapid growth in the population and significant boost to the economy of the colony of New South Wales. The California Gold Rush three years prior signaled the impacts on society that gold fever would produce, both positive and negative. The New South Wales colonial government concealed the early discoveries, but various factors changed the policy.
