Theory of CSI Flashcards
what does ALS stand for
alternate light source
what does FLS stand for
forensic light source
are ALS/FLS portable
most yes
are ALS/FLS used at crime scenes or labs
both
at a crime scene, what will be used to search for evidence (via light)
FLS
are the search results found by FLS conclusive
nope, presumptive (need to be confirmed by lab for DNA)
how do you determine which wavelength to use for ALS
trial and error
describe how to use ALS/FLS photography
- search the scene using the light and note items/areas of interest
- you need to wear goggles (w colour filter)
- setup your camera for photos w a tripod, using the same filter as the goggles youre wearing
- no flash needed
what camera settings are needed with ALS/FLS photography
- otange filter on lens
- high depth of field
- low ISO
- exposure- timed
- will need to try diff time lengths (trial and error) to get right amount of light
- use remote shutter release cord
what did alphonse bertillon do
- created a system of identification based on 11 body measurements (anthropometry)
- standardized the way mug shots were taken
- added profile photo
- developed a method to photo CS and evidence
describe how bertillon’s photoing method worked
- using a high tripod
- decided photos were to be taken before the scene was disturbed
- included a scale along the edges of his photos
when did bertillon do his thing

- created the 1st crime lab in france
- studying fingerprints a bunch too
