The crime scene photographer is responsible for photographically documenting a bloodstain scene in such detail that a bloodstain expert can later do an analysis of the bloodstain evidence. may need almost a 90degree lighting angle to avoid the creation of shadows in the surfaces texture, which would interfere with the recording of fingerprint detail. They can be embedded in a relevant spherical image captured by OSCR360to visually cement their location within the scene. Just follow these steps:1. It is extremely important that photographs of this type are first taken without a scale of reference and then with a scale of reference.

CSI: Scene Documentation - UniversalClass.com While photographing a scene, crime scene technicians try to tell a story with the order in which they take their photographs.

When using an electronic flash to photograph footwear impressions in the snow it is likely your photographs will be underexposed. The technique for photographing a tire impression is similar to photographing footwear impressions. endstream endobj startxref An extreme close-up photograph may be taken of a small item, such as a bloodstain, hair, fabric stain or fingerprint in blood. Remember that the cameras metering system provides settings for normal lighting which is 18 percent reflectance.

Draw an imaginary line between the piece of evidence and the specific fixed feature. The best way to light bloodstain is with oblique lighting. Selfadhesive scales are convenient for photographing tool marks, especially tool marks on vertical surfaces; but a lightweight plastic scale can be taped (using fingerprint tape) to a vertical surface when necessary. Title and information block consisting ofdate/time/case number/agency name, Approximate distance from subject matterin each photo taken, Shutter speed, aperture setting, and ISO for each Photo.

Separate rooms within a building, multiple vehicles at a crash site, and even individual bodies of the injured or deceased may all be considered mini scenes, and should be treated as such photographically.

The depth of tread and imperfections on the sides of the tread are preserved with casting.

This is extremely important for helping investigators to truly understand what the crime scene looked like in its totality. He has testified in superior court concerning his crime scene, evidence, and autopsy photography and has handled high profile cases including a nationally publicized serial homicide case.

He was also the lead forensic instructor at the regional Public Safety Training Facility and a photography instructor at the New York State Academy of Fire Science. Normal contrast photographs can be taken using a professional blackandwhite film such as Kodak TMAX or Ilford Delta Professional films. Investigations Photographs in this category when possible frame the location of the evidence with known landmark (i.e., fixed object, or other item of evidence within the scene).
