Aperture
The camera ______________ is the measure of the diameter of the opening of the diaphragm, and it is adjusted on a film or digital camera by adjusting the f-stop.
Shutter speed
The ______________, measured in fractions of a second, is the length of time the film or microchip is exposed to light.
Depth of field
The ______________ of a photograph is the amount of area in the foreground and background of an in-focus object that is also relatively in focus.
False

True
True or False: Film may be either color print film (producing a negative to be developed), color slide film (producing transparent positives on slides for presentations), black-and white film, or infrared film. ______________
Larger
High-speed films produce grainier photographs because of the _______ size of the film grains.
Microchip
A digital camera captures light on a light-sensitive ______________.
False
True or False: Crime-scene photographers generally use simple "point and shoot" digital cameras. ______________
Barrier
A(n) ______________ filter blocks one wavelength of light bouncing off the subject and allows all others to reach the film or microchip.
Photography log
The ______________, filled out by the crime-scene photographer, should include the case and scene information and the parameters of each photograph.
unaltered
The most important prerequisite for photographing a crime scene is to have it in a(n) ______________ condition.
True
True or False: Each crime scene should be photographed as completely as possible in a logical sequence that includes the area in which the crime actually took place and all adjacent areas where important acts occurred. ______________
overview; medium range; close-up
The succession of photographs taken at a crime scene is ______________ photographs first, ______________ photographs second, and ______________ photographs last.
False
True or False: Overview photographs should include only points of entry and points of exit. ______________
90 degrees
To show the greatest detail of individual objects or evidence, close-up photographs must be taken at an angle of ______________ and with and without evidence markers and scales
painting with light
A technique called ______________ may be used to illuminate long distances in total darkness in night photography.
True
True or False: In indoor or outdoor scenes the crime-scene photographer moves around the boundary of the scene in a clockwise or counterclockwise direction, taking photographs from many vantage points and angles to provide a complete 360-degree view of the scene. ______________

standard operating procedures
To ensure that their digital images will be admissible, many jurisdictions have developed or are developing ______________ for the use of digital photography to avoid the possibility of enhancement or doctoring of crimescene photographs
videotaping
The process of ______________ the crime scene essentially combines note taking and photography.
rough
An investigator need only draw a(n) ______________ sketch at the crime scene to show its dimensions and pertinent objects.
rectangular; triangulation; baseline; polar coordinates
When creating a rough sketch, measurements should be taken from fixed points to pieces of evidence by using either the ______________, ______________, ______________, or ______________ method.
False
True or False: The distances and dimensions shown on the sketch can be a guess or estimate, and the use of a tape measure is not required. ______________
finished sketch
Unlike the rough sketch, the ______________ is constructed with care and concern for aesthetic appearance and must be drawn to scale.
computer-aided drafting (CAD)
______________ programs provide an extensive symbol library and may create a three-dimensional sketch.
