Today, forensic photos are essentials for investigating and prosecuting a crime. This is because most evidence is transitory: fingerprints must be lifted, bodies must be removed and examined, and homes and businesses must be returned to their normal state. Photos help to preserve not only the most fleeting evidence, like the shape of a blood stain that will soon be mopped up, but also the placement of items in a room and the relation of evidence to other objects that are in the room.
Today, digital photography is in the mainstream of camera use. Digital cameras are extremely easy to use and they offer a host of wonderful features. These cameras plug into a PC via USB, so you can upload your pictures easily for archiving, editing and printing. This type of camera makes it simple to share pictures both online and in print. The cameras with resolution in the four-to-five mega pixel range are capable of producing great professional-quality images.
The advantage of digital cameras is the ability to take several pictures at no extra cost and then printing only the best ones. Cameras that were meant for automatic point-and -shoot photos, with a 3x zoom lens will serve casual shooters as well as loyal hobbyists much of the time. Digital cameras with less than one mega pixel are not expensive, but they usually lack important features.
Cameras with higher resolutions of 7, 8, 10, or even more pixels give you the latitude to create larger prints, or to stop and edit images with photo-editing software without destroying quality. All digital cameras have a built-in computer and all of them record images electronically. Since film still produces better picture quality, crime scene investigators have not completely replaced digital with film.
My professional career experience has been in the field of Law Enforcement, as I have served as a police officer for twenty-three years...14-plus years as a Crime Scene Investigator. My ultimate goal is to provide information back to the general public in the form of a book that I recently wrote.
I am offering my first Book, "How To Conduct a Basic Crime Scene Investigation", that details the step-by-step process of crime scene investigation, and keeps the reader in-tune with everything a crime scene investigator should know about a crime scene, from the moment the investigator is notified, until the case is solved!
