Just picked up my SB600 for my first model shoot tomorrow, but have a question regarding the wireless and built in speedlight trigger.
I understand that with the SB600 on wireless, and the built in flash on commander mode, TTL, that the built in flash is adding considerably to the lighting. I'm not sure this is what I want. I'm wishing to use the SB600 as 'fill' moreso than anything, as there should be plenty of natural . I also want to minimise the chance of red eye.
Do I understand correctly that if I want to just use the built in as a trigger but not give (much) to the photo, that I have the D90 built in on 'commander' but change TTL to --. and that will give the signal to get the SB600 to fire but not 'flash' itself?
Alternatively, will I just adjust the built in speedlight power adjustment to -2 or something so it will add a little - still worried about redeye though.
Lastly, in wireless mode, its not showing TTL and/or BL on the display on the SB600 - but do I understand that when wireless its automatically set to ITTL balanced fill flash?
Thanks again all. Hope to post some good pics tomorrow! No guarantees though!
