When processing a digital image for scientific analysis and comparison, there are proper procedures that must be followed.  This is to ensure the processed image’s admissibility in court and to provide the highest level of clarity and detail possible.  Adobe Photoshop provides many tools for processing digital images; however, there are some tools that should not be used in forensic digital image processing.

Analyzing, comparing, and evaluating forensic digital images relies on understanding two essential elements: image quality and image clarity.  Resolution provides image quality, while bit depth provides clarity between the details in an image. It is important to understand how image quality and clarity can affect the probative value of a forensic digital image as well as an examiner’s ability to accurately analyze those images.
