SURFACE TYPES
This basic surface characteristic refers to whether a surface is smooth or rough.
What is texture?
The most common color of fingerprint powder used on light surfaces.
What is black?
This common household adhesive is used in fuming chambers to develop prints.
What is superglue?
This temperature range must be maintained when processing prints in arson scenes.
What is 70-100°F (21-38°C)?
This basic tool provides magnification for print examination.
What is a magnifying glass?
Surfaces exhibiting this characteristic require special consideration as prints may be distorted.
What is curvature?
This brushing technique involves using minimal powder and gentle circular motions.
What is feathering?
SPR stands for this fingerprint development method.
What is Small Particle Reagent?
This method is used to lift prints from adhesive surfaces.
What is gelatin lifting?
This material is used to lift developed prints from surfaces.
What is lifting tape?
This property determines whether a surface will absorb or repel fingerprint residues.
What is porosity?
This type of brush, made from glass fibers, is preferred for magnetic powder application.
What is a fiberglass brush?
This chemical process uses silver nitrate to react with salt in fingerprints.
What is silver nitrate processing?
This chemical is used to develop prints on wet surfaces in underwater recovery.
What is Small Particle Reagent?
This device controls humidity in superglue fuming chambers.
What is a humidifier?
This environmental factor can degrade prints on outdoor surfaces.
What is weathering?
This powder type contains iron filings and is applied with a magnetic wand.
What is magnetic powder?
This process uses heated crystals to develop prints on thermal paper.
What is iodine fuming?
This specialized light source helps locate prints on multicolored surfaces.
What is an alternate light source (ALS)?
This specialized camera attachment is used for print photography.
What is a macro lens?
This surface characteristic describes the molecular attraction between print residue and surface.
What is adhesion?
This specialized powder fluoresces under ultraviolet light.
What is fluorescent powder?
This amino acid reagent fluoresces under alternate light sources.
What is ninhydrin?
This technique preserves prints on bodies in morgue settings.
What is photography before powder application?
This portable device measures surface temperature in arson scenes.
What is an infrared thermometer?
