Manual settings for a noob in Lights, Strobes, and Lighting Technique Posted January 12, 2019 I assume you are turning down the camera's flash exposure to -3.0 to speed recycle and extend battery? Or is it something else? Have you used your set up in TTL mode? My RX100 VI is quite accurate in this mode although you won't be able to turn down your in camera flash comp.... Yes, using manual mode so I can dial the flash exposure down to -3.0 EV in order to conserve battery life.
