Ah, I probably didn't describe my problem properly. The reason for mentioning the built in flash, was to show I can correctly back off 2 stops via flash menu & it all works perfectly. If I now try & do same with SB800 it under exposes the whole shot. I can try using the camera for altering flash stops , or the menu on the Flash itself, but same problem.
All I want to do is lower the amount of fill in flash via the SB800, with everything in Auto mode ..... it should be able to do this from reading the manual (eg. as per my 1st post)
