A radiography system includes a radiography apparatus including first and second radiation detectors and, in a case in which a value corresponding to at least one of a first electric signal or a second electric signal is less than a threshold value, a console derives second imaging conditions using at least one of the first electric signal or the second electric signal, the first electric signal being a signal obtained by converting charge generated in the pixels of the first radiation detector under first imaging conditions, and having a level that increases as an amount of charge increases, the second electric signal being a signal obtained by converting charge generated in the pixels of the second radiation detector under the first imaging conditions, and having a level that increases as an amount of charge increases.
