Level 3 detail includes which elements?

• A. Ridge path details
• B. Ridge attributes: edge shape, width, and pores
• C. Islands
• D. Pores only

Answer: (B)

Ridge micro-features are categorized by the scale of detail available when examining fingerprints. The most detailed information comes from the precise characteristics of the ridges themselves—the way ridge edges are formed, how wide each ridge is, and the presence and arrangement of sweat pores along the ridges. These ridge attributes require close magnification and careful analysis, which is why they represent the most detailed level of examination. Ridge path details, such as where ridges end or bifurcate, fall into a previous level that deals with more general minutiae. Pores alone or islands alone don’t capture the full scope of the fine ridge characteristics, though pores are one component of the detailed features.
