IAI Crime Scene Photography: Questions With Verified
Solutions
Photography involves Right Ans - the creation of an image using light
Composition suggests Right Ans - intentional choosing, not happenstance
Composition will satisfy two goals Right Ans - show the primary subject
most effectively and it will be the viewpoint that excludes as many irrelevant
items and areas surrounding the primary subject
Composition Right Ans - most important and hardest part of crime scene
photography
Before taking a picture Right Ans - choose the primary subject
determine the proper exposure
focus the camera
Three cardinal rules of crime scene photography Right Ans - fill the frame
maximize the depth of field
keep the film plane parallel
If the subject is long or wide Right Ans - choose the appropriate horizontal
or vertical viewpoint
Eliminate distracting backgrounds Right Ans - tilt the camera down more
Eliminate distracting foregrounds Right Ans - tilt the camera up more
Depth of field Right Ans - the variable range from foreground to
background of what appears to be in focus
For crime scene photography Right Ans - maximizing the depth of field is a
critical skill
Smaller aperture Right Ans - larger depth of field range
,Hyperfocal focus Right Ans - when infinity is in the background. Maximizes
the depth of field for large outdoor scenes
Zone focus Right Ans - when infinity is not in the background
Focus by "rule of thirds" Right Ans - maximizes the depth of field for
smaller scenes
Overall pictures Right Ans - exterior are best with the film plane parallel to
the surfaces
Diagonal views Right Ans - makes things larger or smaller or closer adn
father away
Midrange pictures Right Ans - arrange subject and fixed feature as close to
the same distance from you as possible (isosceles triangle or wagon wheel)
Close-up pictures Right Ans - Have the film plane parallel to the evidence is
critical
Exposure stops Right Ans - halves or doubles the overall lighting.
+1 exposure stop Right Ans - doubles the previous exposure
-1 exposure stop Right Ans - halves the previous exposure
Exposure variables directly affects exposures Right Ans - shutter speed
apertures/f-stops
film speed/digital ISO equivalents
flash/ambient light
Proper exposure triangle Right Ans - f-stops shutter speed
flash/ambient light
film speeds
Shutter Right Ans - single lens reflex (SLR) located in the body of camera
where light entering the lens is brought into focus
,Two concepts of single lens reflex Right Ans - image viewed by the
photographer through the viewfinder and the light striking the sensor
Increasing the length the shutter is open Right Ans - images will be lighter
and tend to be overexposed
Decreasing the length the shutter is open Right Ans - images will be darker
and tend to be underexposed
F-Stop sometimes referred as Right Ans - the aperture of a lens of the
diaphragm opening of the lens
The diaphragm of the lens Right Ans - is a set of blades, forming a circular
opening, which can be opened or closed to let more or less light through the
lens
The aperture Right Ans - the size of the resulting diaphragm opening
Graininess Right Ans - lack of resolution from using the improper film
speed
ISO 100 Right Ans - outside sunny day 10am - 3 pm
ISO 100 Right Ans - examination/comparison photos
ISO 400 Right Ans - all other times and indoors photos
DX coding Right Ans - film canister is marked with 12 areas giving
information when inserted into the camera
DX coding contains Right Ans - ISO film speed
number of exposures
exposure latitude of the film
Ambient light Right Ans - light present at the scene
Alter ambient light by Right Ans - using an electronic flash or create a
shadow
, For accurate color capture Right Ans - only use midday sunlight or use a
flash
Shade, cloudy, twilight Right Ans - blue
Sunrise, sunset Right Ans - red
Tungsten Right Ans - yellow/amber tint
Fluorescent Right Ans - green tint
White balance Right Ans - only works on things that are white
Exposure latitude Right Ans - film can not capture all the scenes details in
extreme lighting conditions. More restricted when a digital camera is used
Dynamic range Right Ans - the exposure extremes digital pixels can detect
and record
Film Right Ans - overexpose
Digital Right Ans - underexpose
ISO 100 speed film Right Ans - correctable for a 2 f-stop overexposure and
a 1 f-stop underexposure
ISO 400 speed film Right Ans - correctable for a 3 f-stop overexposure and
a 2 f-stop underexposure
Exposure latitude more restricted Right Ans - when a digital camera is used
Burning Right Ans - adds light or burns areas of a negative that were
previously underexposed
Dodging Right Ans - light is held back from areas of a negative needing less
light than the print as a whole that were previously overexposed
Movement that can be controlled Right Ans - photographer body
movement
