FORENSIC PHOTOGRAPHY
The process of photographing
crime scene or any other

for court presentation.
 TYPES OF
PHOTOGRAPHY
PHOTOMACROGRAPHY
Photographing objects
directly enlarged on the
negative and magnified
from one to nine times.

minutes objects when
magnified by means of a
microscope and enlarge
from 10 times and up.

photographing or
recording unseen objects
by means of infra-red

wherebyexposures are made with
illumination from one or more
photographs.

identification which is the first
use of photography in police
work.

elongated fields of view. It is sometimes
known as wide format photography.
 EVOLUTION
OF
PHOTOGRAPHY
ARISTOTLE (347-322 BC).
A famous Greek philosopher who invented the first
pinhole camera that was known later as Camera
Obscura (Italian word for darkroom chamber)
which
Is literally translated as Darkened Fox.
CAMERA OBSCURA
CAMERA OBSCURA
ALHAZEN (965-1039)
 He found out that light entering a small hole on the wall or
shuttered window of a darkened room cast an upside down picture
of the scene outside onto the opposite wall.
 He was considered to be the one invented the camera.
JEAN BAPTISTE FORTA

 He made used of the Camera Obscura and

replaced the hole with a lens which made the
image brighter and sharper.
 He was the one who introduced the lens.
LENS
JOHANN HENRICH SCHULZE
 A German scientist (Anatomist) who discovered the Silver Nitrate when he
exposed it to light it turned purple.
 He discovered that the evening action was not due to heat but light.
 He finally concluded that Silver Nitrate is sensitive to light and capable of
producing images.
THOMAS WEDGEWOOD (1802)
 He discovered that Silver Chloride is more sensitive than Silver
Nitrate and thus, more capable of recording and producing images.
JOSEPH NICEPHORE NIEPCE
By 1822, he claim some success, achieving what he called Points De Vue – smart
images made by the Camera Obscura with more than eight hours exposure.
 He took the world’s very first photograph called Heliography.
LOUISE JACQUES MANDE
DAGUERRE (1838-1839)
 He invented the principle that Silver plate photograph and using
the Daguerro type that produces one of a kind picture on metal
which was presented by French Scientific Academy.
 He invented the Daguerro type in Paris.
DAGUERROTYPE
WILLIAM HENRY FOX TALBOT
(1839)
 He is the Father of Modern Photography.
 He invented the Calotype which produces a
negative picture on paper, the light on the image
was recorded as dark and dark as light.
CALOTYPE
JOHN F.W. HERSCHEL

 He coined the word Photography.

FREDERICK SCOTT ARCHER
 He pioneered the wet collodian process which took place of the
Collotype known as colodian type process.
DANIEL BARBARO

 He introduced the use of the lens in the camera.

SIR ISAAC NEWTON (1666)
 An English Philosopher, Mathematician and Physicist
who discovered and proved that the strongest light is
white light.
 He defended his theory by allowing a white light
(sunlight) to pass through a prism thus refracting and
diffracting the light onto its component parts.
MADDAOX (1884)
 He successfully introduced the plate with gelatin. The
roll film came and new brands of cameras with different
lens and mechanism were placed in the market.
NADAR
 He took the first Aerial photographs of Paris from a
free balloon in 1858.
SIR WILLIAM ABNEY

 He discovered the use of Hydroquinone as a

developing agent in 1880 in England.
GEORGE EASTMAN

 Introduced the use of roll film made of celluloid

materials for use by a portable camera.
WILHELM ROENTGEN (1895)

 He discovered X-ray photography which later become

the basis of Radiograph used by the doctors in measuring
the heartbeat and to see the other structure of the body.
ALOH ROEMER (DENMARK)
 He measured the speed of light in 1676.
JAMES CLARK MAXWELL.
 A British scientist who discovered the
wavelength structure of light after 20
years of research.
 Colour photographs could be formed
using red, green and blue filters.
ABEL NIEPCE DE SAINT-
VICTOR
 He introduced a process of negatives on glass using
albumen as a binding medium.
LOUIS DESIRIE BLANQUART-
EVARD
 He introduced a printing paper coated with albumen to
achieve a glossy surface.
ODELBERCHT
 He first advocated the use of photography for the
identification of criminals and the documentation of
evidence and crime scenes.
ALPHONSE BERTILLON (1882)

 He initiated anthropometric measurements for personal

identification was also involved in various means of
documentation by photography which developed into a
fine science of Criminalistics when he photographed
crime scenes and formulated a techniques of contact
photography to demonstrate erasures on documents.
DR. R.A. REIS (1902)

 A German scientist who contributed heavily to the use of

photography in forensic science and established the world’s
earliest crime laboratory that serviced the academic community
and the Swiss police.
VICTOR BALTAZARD (1910)
 He developed a method of photographic comparison of bullets and cartridge cases
which act as an early foundation of the field of ballistics.
EDWIN H. LAND (1947)
 He introduced Polaroid – one-step photography.
STEVEN SASSON
 An American Electrical Engineer who
invented the digital camera.
