The Effect Of Photography On Forensic Science

To record a crime scene, forensic scientist can use photography, drawings, and videography. Photographs are an important record of the unaltered crime scene, Drawings or sketches provides valuable information when a photograph cannot accurately depict the scale of a room or the relationship of items to each

The purpose of my study is to give people a chance to understand what is the meaning of photography and how it was invented, plus how people was able to take photographs before the camera was invented.

between a cut (an injury that is longer than deep) and a stab wound (an injury

The shutter speed and the sensor chip are the primary controls for adjusting the amount of light that enters the camera.

Photography serves many purposes and since its invention people have used it for many different reasons, but mostly for

Photography is a word derived from the Greek words photos light and to draw. A scientist called Sir John F.W. Herschel, which was in 1839, first used the word. It was a method which was all about recording images by using light or radiation on a sensitive material. The first known camera was created by Alhazen also known as who lived around 100AD he invented the first pinhole camera this camera was used to capture the movement of the sun. Photography was explained to be the science and art of documenting photographs by capturing light on a light sensitive material which included film or an electronic sensor. Light could be reflected from objects which could expose a chemical or electronic material during a timed exposure which is typically used through a camera which can store the information chemically or electronically. The first photograph was take in 1827 taken by Joseph Nicephore Niepce who made the first photograph

I agree with Ansel Adams. There is so much more to photography then clicking a button. Photography is ideas and creativity through a photo. If I have an idea in my head or a message I want to send across I have to set it up before I even take the picture. There are also many different settings on the camera that help set up a good photo. Photography is a lot of work and different formulas of how everything is set up determines how the photo is going to look. I could be plain with my photography or I can create something with meaning and have it be photographed in a cool, creative way.

One purpose of crime-scene photography is to provide a visual record of virtually everything that was present at the crime scene. When a crime scene occur a photographic record can be used to show elements of the crime scene to those being interviewed or interrogated, so the questioner and those being questioned can have a common understanding of the information that is being exchanged but also secondly the purpose of crime-scene photography is to create a permanent record that can be viewed at any time. Photographs are not only

Forensic science is a broad term that refers to the use of science or technology in a court room environment. Forensic science plays an important role in modern popular culture; the police procedural is highly dependent upon cutting-edge forensic science. Moreover, many people are aware of the impact of DNA testing on the modern criminal justice landscape. However, forensic science actually predates many modern scientific advances; almost as long as there have been controversies, there has been some type of forensic science.

Forensic science borrows from a number of sciences which include: physics, Biology and chemistry. It therefore involves examination of a wide spectrum as compared to any other method of investigation. Due to the wide spectrum of investigation and evidence analysis the method offers; it ensures that the results are accurate and can be used in the court of law to make a decision. The method establishes the existence of a crime, the connection between the crimes and the

While the original Daguerreotype started a massive surge on photography, two later inventions turned photography social phenomenon that became ingrained in our lives today. The first of these inventions is called the “calotype” process. invented in 1839 by William Henry Fox Talbot this method of photography involved exposing chemically treated paper, producing a “negative” that could be redeveloped. This allow for multiple copies of the same image to be printed, and is the predecessor to modern film photography. The next major breakthrough in the art of photography was the portable camera. Before its inception, most photos were taken using a large, cumbersome device that worked as a camera and darkroom for developing glass plates coated with a sticky collodion solution. (film photography was

The photographer that is present at the crime scene is responsible for making one picture worth a thousand words. Photography plays an integral role in the documentation of physical evidence found at crime and accident scenes as well as during forensic autopsies. Forensic Photographers are among the first crime scene technicians to arrive at crime and accident scenes. They walk through a scene to obtain an overview before they begin taking photographs. Forensic Photographers apply their technical skills and their knowledge of anatomy and forensic requirements to take photographs that convey the information that crime scene, criminal, medico legal, or forensic investigators need documented. These

Photographs are created from light rays bouncing off objects. When a person looks through the viewfinder, the image they see are light rays reflected from a penta-prism, a specially shaped piece of glass inside the camera. The rays from the penta-prism came from a mirror, which reflected the rays it received from the lenses. Lenses are used to focus in or out on objects. They attain the rays from the object reflecting the rays toward the camera. For an image to be “captured” on a film camera, the button used to take

Until recently, at least, it was possible to define photography as a process involving optics, light sensitive material and the chemical processing of this material to produce prints or slides. Today though, that definition is subject to change. Technological innovations…are shifting photography from its original chemical basis towards electronics… It is not overstating it to say that the advent of this new technology is changing the very nature of photography, as we have known it. (Bode and Wombell 1991)

Imagine yourself standing on one of the seven wonders in the world. Surrounded by the symbolic scenery you wish to seal up the beauty forever, but you’re struggling due to a lack of knowledge of how to function a DSLR (digital single lens reflex) camera. This user guide will teach you how to use a DSLR camera from the fundamentals, along with in-depth knowledge of the profession functions using the three most important pillars in photography; Aperture, Shutter speed and ISO.
