I have a 5d and 40d. I am venturing over into the strobist world. I will be buying a couple of manual flashes but until I do, I have a question.
My 380ex flash is auto only. I understand this and realize that a manual flash is much more adaptable. I know that manual flashed can go down to 1/8 power, 1/16 power or lower. However, if I use my 380ex with camera in the manual mode, and use auto flash exposure compensation I should get 1/2 power (-1 stop FEC) and 1/4 power (-2 stops FEC). This way I can control ambient exposure with the camera's manual settings and subject’s exposure from 1:1 to 1:4. Correct?
Seems pretty simple but I am asking the flash wizards to correct me if I am missing something important.
Assuming I understand these basics, any other tips in balancing ambient and subject exposure. Does metering mode make a huge difference? (I am currently using e-TTL II in average metering mode.)
Sorry for the dumb questions. Just getting started and have lots to read. Up until now I just set the camera, bang a flash and see what it looks like, then adjust accordingly.
