What is a typical method used to develop a fingerprint at a crime scene?

Dusting is a typical and widely used method for developing fingerprints at a crime scene. This technique involves applying a fine powder, often talcum powder or specialized fingerprint powders, onto the surface where the fingerprint might be located. The powder adheres to the oils and residues left by the ridges of a fingerprint, making the print visible. Once the fingerprint is dusted, it can be photographed or lifted using adhesive tape for further analysis or evidence collection.

The effectiveness of dusting lies in its ability to reveal prints on non-porous surfaces like glass, plastic, or metal where fingerprints can be difficult to see. This method is favored by law enforcement due to its simplicity and efficiency in field conditions.
