Thanks. Explains my exposure w TTL-BL,...I think my images were somewhat underexposed. I have a lot of latitude as I shot RAW and in my estimate underexposure was usually less than 1 stop, easily corrected.

I kept iso's between 400-640.
I usually kept shutter speeds 100-200. I often did not get much of the shutter drag look/ motion blur even if I dropped to 1/50 sec likely as the ambient light added little.

Thanks for your input.
