(The setting is retained after the power is turned off.)

light taken into account. Take pictures with the flash in later shootings.

registered and the
indicator turns yellow on the recording information display on the LCD monitor.
You can shoot at this point, but it is recommended that you set the white balance again to get a more
correct white balance value.
