A practical reference for latent print examiners working with degraded, low-contrast, or pattern-obscured prints.
Enhancement is a routine part of latent print examination. But when a defense attorney asks what was done to an image, and in what order, the tools you used and how you documented the work matter as much as the result itself.
This guide walks through two scenarios examiners encounter regularly, the specific Digital Forensic Suite™ (DFS) tools that apply to each, and how non-destructive enhancement keeps your work tied to the case record and defensible in court.
What’s Inside
Scenario 1: Prints on patterned surfaces.
Fabric, tile, textured plastic. Surfaces where background interference competes directly with ridge detail. Learn how FFT filtering targets and reduces that interference without affecting the print beneath it.
Scenario 2: Prints in difficult lighting conditions.
Detail that looks absent is often present in the image data. Learn which tools recover it and how to approach the problem from multiple angles when a single brightness adjustment isn’t enough.
A tool-by-tool breakdown for each scenario.
Brightness and contrast, curves, black and white, channels, invert, and annotation. Each tool mapped to the specific problem it solves so you know what to reach for and why.
Non-destructive workflow from start to finish.
How DFS keeps the original image intact, saves timestamped versions, and ties every enhancement to the case record so you can account for the work when it counts.
