| description | Photograph that is suspected to be forged one is occasionally encountered
by the forensic practitioner for identification. This kind of examination is one of the
most challenging problems in forensic photography. This identification is
dependent on the existence of certain characteristics like inconsistencies in
magnification, contrast and perspective. The study is intended to probe further into
the salient features of photograph that can be used to identify a composite/forged
photograph. The study is limited to composite/forged photograph produced by
conventional montage techniques.
Photography experiments demonstrating the variation as a result of
changes in focal length, aperture (f-stop number), object distance, lighting,
shadow formations and film ISO film rating are performed. Important features that
could be used in the identification of a composite/forged photograph were
documented.
A questioned photograph has been produced with photomontage
technique. This questioned photograph is forensically examined and identified as
forged a one. |
