Hi A quick question for you. My SB-700 works in TTL-BL when Matrix or Centre-Weighted metering is selected, to set it to TTL (which I have read is good for indoors when you only need to correctly light your subject) I need to select spot metering. Does this mean that I will be using the small spot metering area for my shots? I am thinking if I am in a party situation it may be difficult to try and pick up a mid-tone for the spot to work off of. Or does it use this mode just to select TTL and it actually uses a more centre weighted area to meter?
