Tested a setup with 2 lights and reflectors.
Left of camera is full-length reflector (1.5m height) + 1/1 SB700
Right of camera is 80cm circle reflector + 1/16 SB800
About 1m away from subject. Note that focus is not accurate since done manually in quite dark setup.
Discovered I need to watch my histogram more carefully as I seemed to always get the pictures
underexposed by about 2/3 stops than what I like to have.
