Flash photography problems

Use of flash device may affect the image in many ways.

• White balance errors. The image may get a wrong tone due to mixing of flash colour temperature and

ambient lightning. This is unwanted but normal feature.

• Dust reflections. Dust or water drops in front of the flash unit may reflect strongly to the camera sensor. See

the following figure.
