Digital images are pictures processed through a computer. The images can be created in several ways. The most obvious way is with a digital camera, which creates images that are eventually downloaded and stored on a computer. Another popular way is to scan a photograph directly into a computer. Scanning converts original film photographs into digital images that can be stored, e-mailed or enhanced. Digital imaging offers the user a convenient and efficient means of collecting and cataloging evidence. Images can be delivered via e-mail, saved on disks and CDs, or added to a searchable database. If a digital camera is used to capture the images, there is no need for a chemical lab to develop film. Another advantage to digital cameras is that photographs can be accessed on the scene. Traditional film, however, still provides the highest resolution images and gives the operator more control over the picture-taking process. As the technology involved with digital cameras becomes more advanced and inexpensive, these drawbacks should disappear. The International Association for Identification has formally recognized digital imaging as a "scientifically valid and proven technology for recording, enhancing, and printing images." Manipulation arguments by defense attorneys are not new, and can be overcome through the credible testimony of an expert witness. A preventive measure to counter these arguments is to ensure that a police agency has a standard operating procedure for taking and handling digital images. At trial, prosecutors should focus on the image and the witness, not the technology, unless challenged. 27 notes
