rooms or other compact areas.
A 28 to 35 mm lens is considered a wide–angle
lens for a 35mm camera.
4. Electronic Flash :- Electronic flash,
especially with TTL exposure
measurement provides additional
light that is often needed when
photographing indoors, outdoors at
night, filling in shadows in bright
daylight scenes and for lighting
evidence.
5. Scale and Tape Measure :-
Different scales, containing 6 inch and
36 inch sizes should be taken for
snapping diverse kinds of objects.

6. Videography :
 It is the routine process of crime scene Documentation.
 Its acceptance is widespread due to its ability to provide a virtual image

user-friendly features such as DVD recording, built-in stability, digital
zoom lenses, and compact size.
 Document the recording by using a placard that include the case number

which to measure. Specially used for
