(When the background goes unrecorded because of under- or overexposure)
A photograph can remain eligible for the “Guaranteed TCQ” label even when it is recorded in a situation in which the background is “blown out” to full white (the background is overexposed, for example when exposing for the subject’s face with a bright overcast sky in the background) or “blown out” to full black (the background is underexposed, for example lighting the subject with flash while standing outdoors at night).
See FAQ #784 for more on dynamic range in TCQ photographs.
Note that unlike blown-out backgrounds, cutout backgrounds always disqualify photographs from TCQ.
See also the def|pen brief for background on why TCQ allows backgrounds to be “blown out” but not “cut out.”
