Tip for NoiseAdVisor TWA: In the time inputs, some gadjets apply a pattern of hh: mm: ss followed by AM or PM. So, to enter 00: 30, that is, 30 minutes of exposure, for example, one should use: 12: 30 AM In case of working with exposures above 12 hours when, for example: exposure time of 14: 30, the value 02: 30 PM should be used.
