Participants will conduct facial comparisons, examining images to determine whether they represent the same source or a different source. Participants are not limited to only on-screen comparisons and may use any other method; however, due to differences in printing technology, CTS cannot guarantee the quality of images printed from digital media.

Sample Description: A digitally downloadable .tif file that contains pairs of digital facial images.

Digital test materials are made available in March.

Additional Information: Samples for digital testing, as well as response forms for all test formats, are only available on www.cts-portal.com. The information necessary to access the test materials will be provided via email to the primary contact on file on the day of the test release.
