Alhazen (Ibn Al-Haytham) - a great authority on optics in the Middle Ages who lived around 1000 AD, invented the first pinhole camera, (also called the Camera Obscura } and was able to explain why the images were upside down.
Angelo Sala - a self educated chemist, he discovered that when paper contained powdered silver nitrate it would react with sunlight, causing it to darken. These pioneering experiments with silver salts were a
crucial step towards the later invention of photography. He published his findings in a pamphlet in 1614.
Anna Atkins - (1799- 1871) an English Botanist, she is considered to be the first female photographer.
Aristotle - he observed and noted the first casual reference to the optic laws that made pinhole cameras possible, around 330 BC, he questioned why the sun could make a circular image when it shined
through a square hole.
Arthur Fellig - (Weegee) became famous because of his frequent, seemingly prescient arrivals at scenes only minutes after crimes, fires or other emergencies were reported to authorities.
Carl William Scheele - (1742-1786) Swedish scientist, self-educated. He used to work as an assistant in pharmacies and showed a talent in chemistry from a very young age. In spite an offer made to him to
study in London or Berlin, he operated a pharmacy in Kφping where he spend the rest of his life and made all his important inventions. He was especially interest on chemical analysis and worked particularly with the chemical reactions between silver nitrate and sunlight, therefore making a break through in the chemistry of photography. The records from his experiments were of a great importance for the next generations of scientists.
Digital photography - uses an array of electronic photo detectors to capture the image focused by the lens, as opposed to an exposure on photographic film.
Emulsion - is a mixture of two or more liquids that are normally immiscible (nonmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids.
Exposure - is the amount of light per unit area (the image plane illuminance times the exposure time) reaching a photographic film, as determined by shutter speed, lens aperture and scene luminance.
Film Speed - is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system.
Forensic Photography - (forensic imaging)(crime scene photography) it is the art of producing an accurate reproduction of a crime scene or an accident scene using photography for the benefit of a court or to aid in an investigation.
Frederick Scoff Archer - an English sculptor who invented the wet plate negative in 1851. Using a viscous solution of collodion, he coated glass with light-sensitive silver salts. Because it was glass
and not paper, this wet plate created a more stable and detailed negative.
Gelatin - It is used to hold silver halide crystals in an emulsion in virtually all photographic films and photographic papers.
George Eastman - he invented in 1889 a film with a base that was flexible, unbreakable, and could be rolled. Emulsions coated on a cellulose nitrate film base, such as Eastman's, made the mass-produced
box camera a reality.
Hamilton Smith - he patented in 1856 the Tintypes, another medium that heralded the birth of photography. A thin sheet of iron was used to provide a base for light-sensitive material, yielding a positive image.
---Tintypes - are a variation of the collodion wet plate process. The emulsion is painted onto a japanned (varnished) iron plate, which is exposed in the camera.
Heliographs - (sun prints) were the prototype for the modern photograph.
Henry Fox Talbot - an English botanist and mathematician and The inventor of the first negative from which multiple postive prints were made.
Hercules Florence - (1804-1879) Few details are known for his life. In 1824 goes to Brazil and takes part in a scientific mission at the Amazon, where he becomes preoccupied with the idea of recording images from his trip. From 1830 devotes himself to research and experimentation for photography. The above, gives Brazil the ability to claim that is one of the places in the world, where photography
was found.
Hippolyte Bayard - (1807-1887) The most unfortunate from the pioneers of photography. Discovered one direct positive photographic method. He was the first person to hold a photographic exhibition (for
humanitarian reasons) and the first who combined two negatives to created one print (called Combination Printing). As a civil servant and with five hundred franks that received as financial help from Arago for improving his method, prevented him from presenting the discovery of photography at the French Academy of Sciences.

History of Photography - Timeline
Ancient Times: Camera obscuras used to form images on walls in
darkened rooms; image formation via a pinhole
16th century: Brightness and clarity of camera obscuras improved by
enlarging the hole inserting a telescope lens
17th century: Camera obscuras in frequent use by artists and made
portable in the form of sedan chairs
1727: Professor J. Schulze mixes chalk, nitric acid, and silver in
a flask; notices darkening on side of flask exposed to sunlight.
Accidental creation of the first photo-sensitive compound.
1800: Thomas Wedgwood makes "sun pictures" by placing opaque objects
on leather treated with silver nitrate; resulting images deteriorated
rapidly, however, if displayed under light stronger than from candles.
1816: Nicéphore Niépce combines the camera obscura with
photosensitive paper
1826: Niépce creates a permanent image
1827: Joseph Nicephore Niepce made the first known photographic
image using the camera obscura. The camera obscura was a tool
used by artists to draw.
1834: Henry Fox Talbot creates permanent (negative) images using
paper soaked in silver chloride and fixed with a salt solution.
Talbot created positive images by contact printing onto another
sheet of paper.
1837: Louis Daguerre creates images on silver-plated copper, coated
with silver iodide and "developed" with warmed mercury; Daguerre is
awarded a state pension by the French government in exchange for
publication of methods and the rights by other French citizens to use
the Daguerreotype process.
1841: Talbot patents his process under the name "calotype".
1851: Frederick Scott Archer, a sculptor in London, improves
photographic resolution by spreading a mixture of collodion
(nitrated cotton dissolved in ether and alcoohol) and chemicals on
sheets of glass. Wet plate collodion photography was much cheaper
than daguerreotypes, the negative/positive process permitted unlimited
reproductions, and the process was published but not patented.

Infrared Photography - the film or image sensor used is sensitive to infrared light.
Johann Heinrich Schulze - (1687 - 1744) he was a German professor at the University of Altdorf. He was the first person to produce Photograms, which were created by using paper masks in direct contact
with a jar containing a mixture of silver nitrate powder and chalk. Schulze proved that the darkening of silver nitrate was caused by light and ruled out the possibility of the change being caused by temperature, by observing no tonal change to silver nitrate when heated in an oven.
Joseph Nicephore Niepce - made the first photographic image with a camera obscura.
Latent Image - is an invisible image produced by the exposure to light of a photosensitive material such as photographic film.
Louis Daguerre - a Frenchman and A professional scene painter, was able to reduce exposure time to less than 30 minutes and keep the image from disappearing afterwards. He was the inventor of the first practical process of photography.
Mugshot - (police photograph)(booking photograph) is a photographic
portrait typically taken after a person is arrested.
Negative - is an image, usually on a strip or sheet of transparent plastic film, in which the lightest areas of the photographed subject appear darkest and the darkest areas appear lightest.
Parallax - is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those
two lines.
Photography - It is a method of recording images by the action of light, or related radiation, on a sensitive material.
Photographic Film - (Film) is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals.
Point-and-Shoot Camera - (compact camera) is a still camera designed primarily for simple operation.[1] Most use focus free lenses or autofocus for focusing, automatic systems for setting the exposure options, and have flash units built in.
Rogues Gallery - is a police collection of pictures or photographs of criminals and suspects kept for identification purposes.
Shutter Lag - is the delay between triggering the shutter and when the photograph is actually recorded.
Shutter Speed - (exposure time) is the length of time a camera's shutter is open when taking a photograph.
Silver Halides - The light-sensitive chemicals used in photographic film and paper.
Single-Lens Reflex Camera (SLR) - typically uses a mirror and prism system (hence "reflex", from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will
be captured, contrary to viewfinder cameras where the image could be significantly different from what will be captured.
Sir Humphry Davy - (1778-1829) Chemistry genius, friend and assistant of Wedgwood in his experiments whose results were published at Royal Society, in 1802 by Davy. The problem of "fixing" the images remained in spite of Davy's breakthroughs in chemistry.
Sir John F.W. Herschel - a scientist who first used the word photography in 1839. The word photography was derived from the Greek words Photos, which means light and Graphein, which means to draw.
Snapshot - is popularly defined as a photograph that is "shot" spontaneously and quickly, most often without artistic or journalistic intent.
Thomas Wedgwood - (1771 - 1805) an Englishman who made good ground creating Photograms and recording images from his Camera Obscura or pinhole camera, However, he never overcome the problem of fixing the image and therefore the prints produced had to be viewed for very short periods of time in a darkened environment.
Twin-Lens Reflex Camera (TLR) - is a type of camera with two objective lenses of the same focal length.
Viewfinder - is what the photographer looks through to compose, and in many cases to focus, the picture.
