, Introduction
In this photographic portfolio it’s to demonstrate the using different settings on
the provided cannon camera in a mock crime scene. photo examples in the
portfolio demonstrates the changes of different settings of the ISO, shutter speed
and the aperture in order to get an idea of how these settings can be used and
improve the qualities of the photos so it can be used as evidences.
technical background
Camera are wildly used in crime scenes investigation this is because crime
scene photographers must take high quality technical photographs to insure the
photographs can be used in later investigations and as evidence in courts.
Technical photographs are used to show more detail or information of the object .
technical photographs have four characteristics and these are correct exposure,
maximum depth of field, free from distortion and sharp focus. These four
characteristics can be achieved by the settings of ISO, aperture and shutter
speed. (Staggs, 2021)
Setting of ISO
ISO is stand for international standards organisation. ISO measures the
sensitivity of the image senser. the lower the number the less sensitive the
camera is to light and the finer the resulting grain. On the other hand the higher
the number more the sensitive to light and this allows the camera to be used in a
darker situation. (Rowse, 2021)
