Hi,
Thanks for your mail.
Regarding to the problems of bounce flash and underexposure, after test, it is mainly caused by the metering mode of ETTL flash. Generally, when the flash working with the camera to proceed ETTL flash, there are two metering modes----”Evaluate “ and “Average” metering. The ”Evaluate “metering mode is suitable for Positive flash; while the “Average” metering mode suitable for bounce flash. The default of YN568EX II flash is adopting ”Evaluate “metering mode.So, when you using bounce flash, the metering mode will cause the deviation of flash effect. Meanwhile, we suggest you manually set to “Average” metering mode through the camera. It will avoid the severe underexposure problem.
Best regards.
