The cause and solution may include one of the following:
- The flash is not needed. Change to Flash Off or decrease the flash compensation in any of the PASM modes (certain cameras only).
- The subject was too close for flash. Move so that the distance between you and the subject is within the effective flash range.
- There is too much light. Decrease the exposure compensation. If you use flash, adjust the flash compensation in any of the PASM modes (certain cameras only).
- Auto-exposure was not set. Press the shutter button halfway and hold. When the AF/AE indicator turns green, press the shutter button completely down to take the picture (most cameras).
