This option determines the slowest shutter speed available 
when using front- or rear-curtain sync or red-eye reduction in 
programmed auto or aperture-priority auto exposure modes 
(regardless of the setting chosen, shutter speeds can be as slow 
as 30 s in shutter-priority auto and manual exposure modes or at 
flash settings of slow sync, slow rear-curtain sync, or red-eye 
reduction with slow sync).
Choose how the camera adjusts flash level when exposure 
compensation is used.
