(3) The fire's progress. Continue to document the fire as it spreads
and is brought under control and extinguished. Use color film to photograph
overall views that include the color and quantity of smoke and the color and
size of flames. The color of the smoke and flames often indicates the type
of material that is burning and whether an accelerant, such as gas, was used
to speed the burning.
It is important to keep notes of the time each
picture is made.
(4) Once the fire is out, be prepared to photograph medium and close-
ups of the rubble in the building. Some key things that pictures will be
required of are incendiary devices and combustible materials such as match
books, paper, and liquids such as gas and paint thinner. Fuses even though
burned completely may have left a visible trail.
Photograph defective
wiring and electrical and gas appliances which may have been the cause. The
investigator will point out and help you identify these things. Remember,
take notes for each picture caption.
c. Special Exposure Requirements. If you have never taken pictures of
blackened and fire-charred material, you will be surprised/shocked by the
amount of light these materials absorb.
(1) The exposure required may be two stops more than indicated by
normal exposure calculation methods. This is true even for close-ups and if
using flash.
(2) When using flash, hold the flash to the side as much as an arm
length to bring out surface texture of the burned material or heat-blistered
painted surfaces.
(3) Return to the laboratory and process your film as soon as
possible to ensure you have good exposures.
If not, return to the scene
immediately and using your notes, reshoot as necessary.
(4) Keep the investigator informed and let him know when you have
obtained good pictures/negatives.
11. Possible Emotional Effects.
Investigative photography can be an emotionally disturbing assignment.
Confusion and excitement compounded by the sight of severe wounds,
fractures, burns, mutilation, and even death can cause nausea and even
fainting. You must prepare yourself and maintain self-control; think about
the photographic demands of the mission.
You must remain calm under the
very serious conditions which you may encounter.
