Once video frames of pre- and post-event surveillance have been captured, it is easy to use both Corel Photo-Paint X3 and Adobe Photoshop CS to analyze whether specific items have been moved, removed, or added to a crime scene. This type of information is important because it indicates specific areas or items to be processed for physical evidence. The author offers step-by-step instructions for using both Corel Photo-Paint X3 and Adobe Photoshop CS to analyze pre- and post-event surveillance video frames. First, video frames of the event must be captured and isolated. The first frame should capture the scene immediately prior to the incident while the second frame should capture the scene immediately after the incident. Next, the specific set-up procedure is described, which is the same for both Corel Photo-Paint X3 and Adobe Photoshop CS. The author describes how to access the menus for the Corel Photo-Paint filters and the Adobe Photoshop CS filters. Before closing, the author presents three main scenarios for when pre- and post-event video frames should be compared: (1) when surveillance video is recording at a low frame rate; (2) when interior lights are turned off and the incident occurs in the dark; and (3) when the investigator or analyst feels it may prove beneficial.
