Forensic light source is commonly used for enhancing evidence in a nondestructive way. Latent fingerprints play an important role in an aspect of crime scene investigation. In this study, researchers compared enhancement of standard fingerprints treated with DFO and 1,2-IND in accordance with laser and LED light sources. As a result, laser light source has a better effect rather than LED light sources. However, each light source has strengths and weaknesses in terms of performance and portability. Therefore, researchers recommend that crime scene investigators need to use laser and LED light sources depending on the situation.
