In order to use one SB-700 Speedlight, off-camera with a D7100 and with no additional equipment, do you have to be in COMMANDER MODE? I'm trying to identify the easiest way to control the SB-700 manually (non-TTL) off-camera. With that objective in mind, is there another option besides the COMPENSATION setting within the COMMANDER MODE menu on the D7100? The SB-700 has an EV setting adjustment available when placed in the ON mode, but not in REMOTE mode, and it apparently has to be in REMOTE mode to be used off-camera. Also using this same configuration, I'm assuming the flash compensation on the D7100 only affects the pop-up flash. Correct? Last, does the MANUAL setting on the upper left side of the SB-700 have any applicable function within this scenario (i.e. off-camera, with a D7100 and only one speed light).
