Day 1 Flashcards
The camera of choice for crime scene photographers is:
Single Lens Reflex (SLR)
- extremely versatile
- Interchangeable parts and can upgrade
- used in variety of situations and including low light
- capable of shooting 30 second photographs
The infinity symbol means:
Maximum distance of focus with camera lens
-focus based on distance
The filter ring size has nothing do with focal length but refers to:
Diameter of lens threaded end
Flashes are graded by their power_______________.
Guide number
Shutter priority refers to:
User picks shutter speed and camera picks aperture for proper exposure.
Aperture priority refers to:
User picks aperture and camera picks shutter speed for proper exposure.
Maximum aperture is 3.5 for 18mm lens is:
1: 3.5 - 5.6
In the Program mode, the user decides:
If flash is needed
The actions of light are:
- Absorption
- Reflection
- Refraction
The visible light range is:
400NM to 700NM
UV light is greater than:
400NM
Infrared light is greater than:
700NM
Reflection is when the angle of incidence equals angle of___________
Reflection
Exposure value is:
When the stop of light is equal to 1/2 or 2X the amount of light to the next full stop of light.
Camera determines or converts exposures to:
18% Gray
Camera uses reflective meter to evaluate light by attempting to base correct exposure on:
18% Gray
Best shutter speed to stop motion is:
1/1000 fastest speed
If a subject is largely white it is at risk of being:
Under exposed
Shutter priority is used to________.
Stop motion.
Bracketing captures an image with:
Varying degrees of light
Black and white photography has applications in:
UV, Infrared and fingerprint
ISO 100 setting has the best:
Color saturation and sharpest image
The advantage film has over digital photography is:
Higher Dynamic Range
Film could be a better choice than digital for:
Extraordinary Long Exposures
The exposure value is___________________
Stop of light is equal to 1/2 or 2X amount of light to the next full stop of light.
Reciprocity Failure is________________
After 4 seconds film or image should be twice as bright but is not.
Zone of sharp focus will_________________
Extend 1/3 forward from point of focus and 2/3 to the rear.
Factors that affect depth of field are:
- Aperture
- Lens choice
- Subject to camera distance
Rule of thumb when hand holding camera:
Shutter speed should be 1 over focal length of lens to prevent camera shake.
Long range photographs show_________________
Location of crime scene
Mid- range photographs show:
Relationship between evidence and scene
Close-Ups show:
Single piece of evidence
Examination photographs are done with___________
A scale to show one to one comparison and shot at 90 degrees
Improving composition of depth of field greatly improves ________
Mid-range relationships in photographs
