How do I make a Nikon D7100 release the shutter even if autofocus hasn’t locked?

On our Nikon D7100 in Program mode, the shutter sometimes won’t fire. It seems to happen when the subject has low contrast, even though it looks in focus through the viewfinder. We’re using a Nikon 16-85mm lens in autofocus with VR on, and staff need to keep using Program mode rather than Manual exposure.
How can we set the camera so pressing the shutter always takes the photo, even if autofocus can’t confirm focus?

If you set the AF-C and the AF-S priority to Release, this will enable you to take photos irrespective of focus/color/contrast. These settings are accessed by Menu/Custom Settings/Autofocus/a1 AF-C priority and Menu/Custom Settings/Autofocus/a2 AF-S priority. They should both be set to Release.
It is all on page 231 of the D7100 User Manual (p.259 of the PDF document which includes 28 prefix pages prior to page 1).

Yes — this is controlled by the D7100’s autofocus release priority settings, not by Program mode itself.
Set both autofocus priorities to Release:
- Menu > Custom Settings > Autofocus > a1 AF-C priority selection > Release
- Menu > Custom Settings > Autofocus > a2 AF-S priority selection > Release
With these set, the camera will allow the shutter to fire even if autofocus hasn’t achieved focus confirmation, which is useful in low-contrast situations where AF may hesitate.
Program mode can still be used normally; you do not need to switch to Manual exposure mode to change this behavior.
