The search for possible fingerprint needs a systematic and narrowly approach to the suspected areas.

✔Fingerprints can frequently be seen by holding the flashlight🔦at low angles so that the surface is observed under oblique lighting.

✔Observation under white light may reveal latent fingerprints that can be photographed without any further treatment.

✔In some cases, latent print can often be detected using episcope coaxial illumination. The print is, therefore, visible as dark ridges against a light background.

✔A magnifying lens🔎 is useful to locate and judge the quality of the fingerprints.
