PHOTOGRAPHS AND CRIME SCENE SKETCHES
Is one of the most significant since it can be applied in all allied branches of it.
FORENSIC PHOTOGRAPHY
Plays a very significant role in preserving evidences necessary in the prosecution of criminal cases.
PHOTOGRAPHY
Is to provide a true and accurate record of the crime scene and physical evidence present by recording the original scene and related areas.
CRIME SCENE PHOTOGRAPHY
Is an integral part of trial. And the judgement often is based upon crime scene photographs to prove prima facie evidence.
FORENSIC PHOTOGRAPHY
Is an indispensable tool to effective presentation of certain types of courts testimony. Exhibits of handwriting, fingerprints, bullets, traffic vehicular wreckage are integral parts of court testimonies, so always remember that opinion of the expert witness is always susceptible to ocular inspection, otherwise, his testimony would have a lesser weight.
PHOTOGRAPHY
Was first coined by Sir John Herschel who first used the term in 1839 the year that the photographic process became public.

PORTRAITURES
Basic importance of Crime Scene Photograpy
- REFRESH MEMORY
- PRESERVE TIME AND EVENT
- SAVE MONEY
A photograph is used to identify a suspect, victim, or place where crime was committed, weapons used in the crime, etc.
IDENTIFICATION
A photograph of suspect, witness, victim of a crime scene serves as a permanent record.
RECORD
The photographic record of evidence found at the crime scene well presented in court for the understanding of every party who have interest the case.
PRESENTATION
Evidence which cannot be brought to court for exhibit by reason of size, weight, height, and permanency of location this will be substituted by a photograph.
SUBSTITUTION
A good photograph can be the deciding factor in conviction or acquittal of the suspect when no other form of real evidence is available.
DECIDING FACTORS
Is a mechanical result of photography. Light is needed aside form sensitized material (film or paper).

ULTRAVIOLET PHOTOGRAPHY
Discovers that white light is composed of different colors: red, orange, yellow, green, blue and violet.
ISAAC NEWTON
He is the first to understand the rainbow - he refracts white light with a prism, discovers that white light is composed of seven distinct colours.
ISAAC NEWTON
A professor of anatomy, after a number of experiments discovered that silver salts, specifically a piece of chalk dipped in silver nitrate turned black from white when exposed to the sun. The unexposed side remained white.
JOHANN HEINRICH SCHULZE
He experimented creating crude photographic impressions, but eventually it all turned black due to exposure.
JOHANN HEINRICH 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.
JOHANN HEINRICH SCHULZE
The founder of modern astronomy and discovered Uranus and other heavenly bodies.
WILLIAM HERSCHEL
He discovered the infrared region of the electromagnetic spectrum of radiation (light).
WILLIAM HERSCHEL
Exploring the question of how much heat was contained by the different colors of visible light. He devised and experiment where he used a glass prism to separate sunlight into its rainbow of colors. Then, he placed a thermometer under each color, with one extra thermometer just beyond the red light of the spectrum. He found that the thermometer that was seemingly out of the light had the highest temperature. Thus, he discovered infrared light.
WILLIAM HERSCHEL
He suggests the “three color” idea of light. That there are three primary colors blue, green, and red. These three blend together in various combinations to form any other color in the visible spectrum.
THOMAS YOUNG
He was French inventor and most noted as one of the inventors of photography and a pioneer in the field.
JOSEPH NICEPHORE NIEPCE
He developed his process called “heliography”. Created the world’s first permanent image (heliograph) using pewter plates in a camera obscura. It required 8 hours to expose.
JOSEPH NICEPHORE NIEPCE
Which means “sun writing”.
HELIOGRAPHY
A signaling device by which sunlight is reflected in flashes from a movable mirror.
HELIOGRAPH
From Latin, meaning “dark room” or “dark chamber”.
CAMERA OBSCURA
Also referred to as pinhole image, is the natural optical phenomenon that occurs when an image of a scene at the other side of a screen is projected through a small hole in that screen.
CAMERA OBSCURA
He was a British inventor and photography pioneer who invented the “calotype process” a precursor to photographic processes of the 19th and 20th centuries to produce a negative image.
WILLIAM HENRY FOX TALBOT
The father of the negative-positive photographic process.
WILLIAM HENRY FOX TALBOT
His experiments using paper soaked in silver chloride and fixed with a salt solution to create permanent (negative) images of silhouettes. In this technique, a sheet of paper coated with silver chloride was exposed to light in camera obscura.
WILLIAM HENRY FOX TALBOT
Was a French artist and photographer, recognized for his invention of the daguerreotype process of photography. He became known as one of the fathers of photography.
LOUIS-JACQUES-MANDÉ DAGUERRE
Sets up Eastman Dry Plate Company in Rochester, New York. First half-tone photograph appears in a daily newspaper, the New York Graphic.
GEORGE EASTMAN 1880
The first twin lens reflex camera is produced in London. Such cameras employ a viewing lens that is matched to the “taking lens”, and focused by the same mechanism. Rolleiflex are the best-known manufacturer of these.
1880
In 1881 he invents a process for making reproductions in colour - the trichromatic half-tone plate.
FREDERICK E. IVES
1886 develops the half-tone engraving process whereby photographic and other images can be reproduced simultaneously with text.
FREDERICK E. IVES
He was a French cloth merchant by trade, but in the 1840s became a student of photography. He studied calotype process, and in 1847 became the first person to publish the process in France.
LOUIS DESIRE BLANQUART EVRARD
Introduce a printing paper coated with albumen to achieve a glossy surface, to improves and modifies Fox Talbot’s calotype process and sets up a printing business in Lille, France. Albumen paper was never patented and was popularly used for 40 years.
LOUIS DESIRE BLANQUART EVRARD
A sculptor in London. Invented the photographic “collodion process” which preceded the modern gelatin emulsion. He found calotype photography useful as a way of capturing images of his sculptures.
FREDERICK SCOTT ARCHER
Improves photographic resolution by spreading a mixture of collodion (nitrated cotton dissolved in ether and alcohol) and chemicals on sheets of glass. Exposure and processing is performed immediately after coating plate. Wet plate collodion photography was much cheaper than daguerrotypes; the negative/positive process permitted unlimited reproductions, and all from relatively short exposures of a few seconds. The process was published but not patented and Scott Archer died in poverty.
FREDERICK SCOTT ARCHER
The process involved adding a soluble iodide to a solution of collodion (cellulose nitrate) and coating a glass plate with the mixture.
FREDERICK SCOTT ARCHER
Was the pseudonym of Gaspard-Felix Tournachon, a French photographer, caricaturist, journalist, novelist and balloonist. Some photographs by Nadar are marked “P. Nadar” for “Photographie Nadar”.
FÉLIX NADAR
He took his first photographs in 1853 and in 1858 became the first person to take aerial photographs. He also pioneered the use of artificial lighting in photography, working in the catacombs of Paris.

He was an English photographer and physician who invented “light weight gelatin negative plates” for photography in 1871.
RICHARD LEACH MADDOX
Proposes the use of an emulsion of gelatin and silver bromide on a glass plate, creating the dry plate silver bromide process - negatives no longer had to be developed immediately. Exposure times of 1/25th second could be achieved.
RICHARD LEACH MADDOX
Makes a high-speed photographic demonstration of a moving horse, airborne during a trot, using a trip-wire system. From 1884 he begins work at the University of Pennsylvania to produce a massive collection of photographs of animals in motion, ultimately to be published as Animal Locomotion.
