Practice proper crime scene management by applying the twelve step model to a given scenario. Such an approach can help to ensure that the evidence collected meets the rigorous standards necessary for evidence to be introduced into court.
The following twelve-step model is one such approach. Some helpful planning guidelines are: Accumulate packaging and collection materials Prepare the preliminary document. Example paperwork Coordinate personnel assignments Evaluate legal ramifications e.
Select a defined team leader. Assignments should be made with a consideration of attitude, training, and experience of each individual. Depending on the circumstances and personnel available, it may be necessary to assign more than one duty to some team members covered in Roles and Responsibilities.
It is relatively common for one individual to accomplish two or more responsibilities.Toggle navigation. Help Preferences Sign up Log in. View by Category Toggle navigation.

Is there trash in the trash cans?The camera has a long and distinguished history as a means of recording phenomena from the first use by Daguerre and Fox-Talbot, such as astronomical events eclipses for example and small creatures when the camera was attached to the eyepiece of microscopes in photomicroscopy. The camera also proved useful in recording crime scenes and the scenes of accidents, one of the first applications being at the scene of the Tay Rail Bridge disaster of The court, just a few days after the accident, ordered James Valentine of Dundee to record the scene using both long distance shots and close-ups of the debris.
The set of accident photographs was used in the subsequent court of inquiry. They show that, in the words of the Public Inquiry the bridge was badly designed, badly built and badly maintained. Below is a picture of one of the bridge columns.
The methods used in analyzing old photographs are known as forensic photography. History But when did actual crime scene photography begin? Mary Jane Kelly was murdered by Jack the Ripper on November 9, 5th and last victim and photographed in her room. History Alphonse Bertillon started photographing crime scenes around Paris circa Line drawings, half-tone photography, and chromolithography, which could render coloration, texture, and subtle shading, became increasingly common as improvements in print technology made detailed illustrations cheaper to produce.
Photographs taken at a crime scene: 1. Show the layout of the crime scene 2. Show the position of collected and uncollected evidence 3. Show the point of view of victims, suspects, and witnesses 4. Show the original condition of items of evidence at the scene 8.
Film Photography Photographic film consists of a sheet of silver halide grains which expose when exposed to light. Film speed is a measure of the light-gathering capacity of the film. Special types of film include Polaroid film and Infrared film.
A digital photograph is made when a light sensitive microchip captures light on each of millions of tiny picture elements, called pixels. The light is recorded on each pixel as a specific electric charge which is read by the camera as image information which is stored as a file on a memory card. The number of pixels is directly related to the resolution of the picture. Photographs with more pixels show increasingly good resolution, or more detail and sharpness in photographs.
The number of pixels that a camera features is usually measured in millions of pixels, or megapixels. SLR and DSLR cameras also allow for manual adjustment of camera settings, such as aperture and shutter speed, that affect image quality.
The camera lens bends light to focus an image on the film or digital microchip. The lenss focal length, the distance between the lens and the image projected on the film or microchip, determines the area shown in the resulting photograph.
Normal Lens --Focal length of mm and used for most photographs that need to be taken at a crime scene because it can show as much area as half a wall Wide-angle Lens --Focal length of 35 mm and used to show much more area in one photograph than a normal lens. Macro Lens --Focal length of less than 50 mm and used for highly-detailed close-up photographs. Multi-purpose Lens --Focal length from mm used to take normal, wide-angle, and telephoto photographs On film or digital cameras, one adjusts the aperture by setting the f-number --The lower the f-number setting, the wider the aperture and the more light is allowed in.
The shutter speed is the length of time that the film or microchip is exposed to light. Depth of Field The depth of field shown in a photograph is the amount of area in the foreground and background of an object in focus that is also relatively in focus. The smaller the aperture opening, the greater the depth of field will be. This means that higher f-number settings will yield higher depth of field.
The auto mode automatically selects an appropriate f-stop and shutter speed for conditions being photographed. The sports mode captures subjects in motion by using a higher faster shutter speed.Instructional Goal To provide the participant with an understanding of the fundamentals of crime scene management as it pertains to the collection and preservation of physical evidence.
