In such cases, the software author would need to confirm that the color combinations used meet the contrast requirement.
      Photographs (e.g., of a hardware display) are not sufficient for testing that content meets this success criterion. This is because the quality of the lighting, camera, and physical aspects of the hardware display can dramatically affect the ability to capture the content for testing purposes.
