Hi there
With the inon sTTL mimicing the on-camera pre-flash for determining correct flash output and exposure, how does this system work if the camera is set to fully manual (where the pre-flash is turned off- since its manual it doesnt do TTL so no preflash).
I have a canon A570 and am trying to get really familiar with the sTTL on the d2000s
Any info very much appreciated.
