Which statement best describes latent prints on porous surfaces with powders?

Feedback

Powders make residues visible; they do not erase prints, color-code DNA, or sterilize surfaces.

Black powders are standard for non-porous surfaces; other options are not typical powder development methods.

Fluorescent powders require a light source to emit visible glow for easier visualization.

Dusting enables powders to stick to residues; excessive force can obscure details.

Gentle dusting minimizes distortion of minutiae essential for identification.

Non-porous surfaces retain residues well; porous surfaces often require alternative methods.

After dusting, prints are preserved by lifting or photographing; excess powder should be removed carefully.

Soft brushes minimize disturbance of ridge detail while distributing powder.

Dedicated tools and containers reduce cross-contamination between cases.

Porous surfaces often need chemical/fuming methods; powders are primarily for non-porous surfaces.
