BLACK AND WHITE
The word photography comes from two ancient Greek words: photo, for "light," and
graph, for "drawing." "Drawing with light" is a way of describing photography.
When a photograph is made, light or some other form of radiant energy, such as X
rays, is used to record a picture of an object or scene on a light-sensitive surface.
Early photographs were called sun pictures, because sunlight itself was used to
create the image. Mankind has been a maker of images at least since the cave
paintings of some 20,000 years ago. With the invention of photography, a realistic
image that would have taken a skilled artist hours or even days to draw could be
recorded in exact detail within a fraction of a second.

image sensor on the opposite side of the box
- Can have incredibly long exposures! Ranging from
½ second to several hours!
- The produce softer, not so sharp images with no
focal length and a depth of field that is nearly infinite
• First known person to record the formation of an inverted image
was Chinese philosopher Mo Ti
• Aristotle and Da Vinci both commented their use of pinhole
cameras in their work
• Scottish scientist Sir David Brewster was the first to make
pinhole photographs in the 1850‟s and coined the term “pin-
hole” in his book “The Stereoscope”
- Were used by astronomers to study solar eclipses
- Pinhole cameras can be used to photograph high energy X-rays
and gamma rays and were deployed in space crafts in the late
50‟s and early 60‟s to do so, the first being created in April 1960
- Pinholes are still being used but have multiple pinhole optics
- They‟re used by nuclear physicists to photograph high energy in

WHAT IS CAMERA OBSCURA?
• Camera= room obscura= dark
• Light travels in a straight line. When some of the rays reflect from a bright subject, it is
passed through a small hole in thin material. The light does not scatter, but instead
crosses and reforms as an upside down image on a flat surface held parallel to the hole.
WHO WAS INVOLVED IN CREATING CAMERA
• Earliest mention was by the chinese philosopher Mo-Ti (5th century B.C.)
• Aristotle understood the optical of the camera obscura (384-322 B.C.)
• The Islamic scholar/ scientist Alhazen gave a full account of the principle (C. 965-1039)
• In 1940, Leonardo Da Vinci gave 2 clear discriptions of the camera obscura in his
• The mage quality was improved with the addition of a convex lens into the aperture in the
16th century. Later, an addition of a mirror to reflect the image down onto a viewing
surface. Giovanni Battista Della Porta recommended the use of this device as an aid for
drawing in his 1558 book “Magiae Naturalis”.
• The term “camera obscura” was first used by the German astronomer Johannes Kepler in
the early 17th century.
• Mercedes Berger4
WHAT WAS IT USED FOR?
• Sun viewing
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
1725: The first chemically photographic process can be considered a photogram. This was an
accidental discovery. Johann Heinrich Schultze found that silver nitrate impregnated on gypsum
in a jar, when left exposed to sunlight, turned dark on the side facing the window. After exposure,
if the bottle was shaken, fresh silver nitrate replaced the exposed material near the glass surface.
This was an accidental discovery,
1826: Niepce creates permanent image
French inventor Joseph phore pce uses a camera obscura to burn a permanent image of the countryside
at his Le Gras, France, estate onto a chemical-coated pewter plate. He names his technique "heliography,"
meaning "sun drawing." The black-and-white exposure takes eight hours and fades significantly, but an image is
still visible on the plate today.
1816: Nicéphore Niépce combines the camera obscura with photosensitive paper
1827: French inventor Joseph Niepce made the first fixed photographic
images. He used a primitive camera and a bitumen-coated pewter plate
to capture this image of a Set Table, which is one of his earliest
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.
First Negative Image
Taking advantage of a relatively new technology, the daguerreotype, French physicists Louis Fizeau and
Leon Foucault made the first successful photographs of the sun on April 2, 1845.
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.
1855-57: Direct positive images on glass (ambrotypes) and metal (tintypes or
ferrotypes) popular in the US. A thin sheet of iron was used to provide a base for
light-sensitive material, yielding a positive image.
The ambrotype photograph was made by coating a piece of glass with a silver
solution and exposing this to the image. The image is sometimes on the back of a
glass plate and is sandwiched with another glass behind it.

1921: Man Ray begins making photograms ("rayographs") by placing objects on photographic
paper and exposing the shadow cast by a distant light bulb; Eugegrave;ne Atget, aged 64,
assigned to photograph the brothels of Paris
1871: Richard Leach Maddox, an English doctor, proposes the use of an emulsion of
gelatin and silver bromide on a glass plate, the "dry plate" process.
LIGHT SENSITIVE CHEMICALS FOR FILM & PAPER
The light-sensitive substances used in photographic film to record an image are silver salts
and are called silver halides. The silver halides react to ultraviolet radiation, violet, and blue light
only; however, they can be made sensitive to other colors of light and infrared radiation by the addition
of dyes. Depending on the amount of light and the type of silver halide, the light produces a visible or
invisible change in the halides of a film or printing paper. An invisible change is made visible by
Photographic films and papers are composed of two basic parts: the emulsion and the
base, or support. The emulsion is the light-sensitive portion of a film or paper that records the image.
The emulsion contains the silver halides and any special sensitizing dyes suspended in a binder of
gelatin. The gelatin holds the silver halides evenly dispersed and prevents action by a developer until
the silver halides have been made developable either by exposure to light or chemical action. Also, the
gelatin acts as a sensitizer for the silver salts.
Main Chemicals, Compounds, Components
The main chemicals, compounds and components come in when actually developing the
film. The film has four layers: The first layer is a protective coating which protects the
emulsion layer that has the gelatin and the silver halide crystals in it. Higher speeds of film
have multiple layers of emulsion. The third layer is the film base. The film base is a
polymer that is chemically stable and flexible. The fourth layer is the anti-halation backing
which prevents reflections off the back of the film.
Chemicals used to develop the film:
Developer: This substance is what causes the silver iodide on the roll of film to darken as
if it has been exposed to the light.
Developer is made out of two solutions.
*Solution A: 50 ml of water, 1 gram of sodium sulfite, 0.16 grams of
hydroquinone, 4.6 grams of sodium carbonate, and 1.1 gram of
*Solution B: 50 ml of water and 8 grams of sodium sulfite
Stop bath: This substance completely stops the development process
*Stop bath is made out of acetic acid but many people just use water in lieu of
stop bath to reduce the cost.
Fixer: This substance removes all of undeveloped silver iodide from the emulsion
*Modern fixers are usually made out of sodium thiosulfate or ammonium

L.J.M. DAGUERRO AND NICEPHORE NIEPCE
WERE THE FIRST TO MAKE THIS TYPE OF
• First image was produced in 1837 when they found that if a copper plate with silver iodide
is exposed to light in a camera and later fumed with mercury vapor and fixed by a
common salt solution it formed a permanent image.
• By the time the first image was produced, Niepce had died so they went on to name the
process after Daguerro
• Most of the daguerreotypes were made in the mid- 19th century.
• Later, this method was replaced by the wet collodion process in 1851.
THE CALOTYPE PROCESS
• William Henry Fox Talbot discovered the Calotype process in September 1840. He
announced his discovery on 8 February 1841, though at that stage he gave no details of
the process then patented the process later in 1841.
• The attraction of the calotype process was that it enabled a latent image on the paper to
be transformed into an actual image after the paper had been removed from the camera.
• The calotype process allowed much shorter exposures than for photogenic drawing, and
so made portraits possible. Exposures of around 1 to 3 minutes might be required for a
calotype. Talbot's earlier photogenic drawing process might have required an exposure
of an hour.
• So calotype portraits became possible, as demonstrated by Talbot in October 1840 and
by Hill & Adamson in Edinburgh from 1843 to 1847.
• The calotype negative process was sometimes called the Talbotype, after its inventor. It
was not Talbot's first photographic process (introduced in 1839), but it is the one for which
he became most known.
THE CALOTYPE PROCESS
The photographic technique employed by Hill and Adamson was very similar to that still in
use today. A negative was exposed in the camera, developed in a dark room and then
printed on sensitive paper. Their cameras, while wooden and large, are easy to relate to
modern cameras. However, their sensitive materials were quite different from ours in one
important aspect. Modern photographic film and paper are highly refined highly technological
products made under strict controls in a factory setting. In addition to the other problems they
faced, Hill and Adamson had to make each and every sheet of negative or print material by
hand. There are no significant records of their particular working practices. However, we
know they were in close touch with the art's inventor, William Henry Fox Talbot (especially
through their mutual friend, Sir David Brewster) and it can be assumed that their practice
built on Talbot's approach.
The calotype negative process was sometimes called the Talbotype, after its inventor. It was
not Talbot's first photographic process (introduced in 1839), but it is the one for which he
became most known.

• The exposure & development process time window is only
about 10 minutes for the negative.
• Up to 20 second exposure times often created blurred images.
• The positive had to be exposed for long periods in the sun.

SIR JOHN HERSCHEL

Inventor of Cyanotype Photography
Sir John Herschel was a
scientist and astronomer like his
father, Sir William Herschel. In
1809 he entered the University
of Cambridge; in 1812 he
submitted his first mathematical
paper to the Royal Society, of
which he was elected a fellow
the following year. An
accomplished chemist, Herschel
discovered the action of
hyposulfite of soda on otherwise
insoluble silver salts in 1819,
which led to the use of "hypo" as
a fixing agent in photography. In
1839, independently of William
Henry Fox Talbot, Herschel also
invented a photographic process
using sensitized paper. It was
Herschel who coined the use of
the terms photography , positive
, and negative to refer to
In 1820 herschel became a founding member of the royal astronomical society. From 1833 until
1838, his astronomical investigations brought him and his family to the cape of good hope in
south africa, where he met julia margaret cameron, who became a lifelong friend. In 1850
herschel was appointed master of the mint, but he resigned six years later due to poor health.
His remaining years were spent working on his catalogs of double stars and of nebulae and star
• Rather than silver, the cyanotype relies on
iron chemistry for its distinctive Cyan/Blue
image. It is still popularly known as a „sun
print‟ or „blueprint‟. Being easily developed
in water after prolonged exposure to UV
light, the sun print is many people‟s earliest
meeting with photosensitive materials in
school. Cyanotypes are usually associated
with photo grams but they can be used with
conventional negatives to produce full-toned
images. The Victorian photographer Anna
Atkins first used the process
photographically in a series of cyanotype
books documenting ferns and leaves. It is
perhaps one of the easiest alternative
processes to try but also one of the most
difficult to perfect.
