What is the purpose of photographing a latent print prior to lifting?

The primary purpose of photographing a latent print prior to lifting is to preserve the latent image in case it is lost during the lifting process. Photographic documentation ensures that there is a record of the original print, capturing its details before any physical attempt is made to lift it from a surface. This is particularly crucial because lifting methods, whether using tape or powders, can sometimes disturb or damage the latent print, leading to a potential loss of critical evidence.

Photographs taken beforehand can serve as an irreplaceable reference and can be particularly important in cases where the lifted print does not retain all its original characteristics. Additionally, having a photographic record allows for the possibility of re-examination or further analysis at a later stage, which is vital in an investigation.

While enhancing print quality, assisting in digital analysis, and using images for court presentations are all valuable aspects of photographic evidence, they are secondary to the foundational goal of ensuring that the latent print is recorded accurately before any lifting techniques are applied.
