Jim,



the camera's flash or the SB-600 need to be in manual mode, not TTL. Is this what you mean by "camera preflash turned off"?

Thanks..



Sorry, I should have said 'modelling illumination', not preflash - but I now realise that's irrelevent as it's fired manually by the DoF preview button (book says).



However, I have now changed to MANUAL (on-Camera) trigger flash, as you kindly suggest, at 1/128th power - big improvement!... But still 2 stops difference between PC and slave ????



Dratt. Well we're moving in the right direction



Thanks again
