To ensure the
best functionality of the Camera Ballistics software we advise you to use raw
and unedited photos with higher resolution. To create a fingerprint please use
photos with the same resolution as the photos that are currently being
investigated. If the resolution differs, we are unable to ensure that the
fingerprint stays the same since the camera may behave diffrently on various
resolutions. This may cause problems with identification resulting in photos
not being correctly matched to the fingerprint.
If the photo was
obtained from the messaging application, it is highly possible that the
fingerprint of the photo has been modified. Due to modications ongoing during
the sending process, like resolution change, change of file format or color change.
If you were to create a fingerprint from photos that have gone through the same
modifications like the investigated file. For example sending them through the
same messaging app as the investigated photo. This could result in creating of
the same or similar fingerprint as of the investigated photo. We cannot ensure
the maximum similiarity of the fingerprints because the apps may handle various
types of photos differently. Keep on mind that in this case you will need more
photos to create the fingerprint because of the lower resolution.
the thumbnail and raw original photo will be marginally different. Same as with
the messaging apps, you would have to let the photos be edited by the same
process of modification as the investigated file. To achieve this, you would need
a high amount of photos. We still would not be able to ensure the same quality of
the fingerprint as with higher resolution photos. With resolution this low it
is highly unlikely that the photo will preserve its original fingerprint and
may rapidly change in different shots.
