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.
More detailed information of flash photography problems can be found in the document “LED flash service
manual”.
