I have a D850 with the Nikon's wireless transmitter, and a SB-5000 flash. I cannot figure out how to use the flash over radio, and at the same time shoot in the manual mode, where I can specify the flash power. Everything is working fine in remote TTL mode, but when I switch my flash from my camera from TTL to the manual mode, I don't see how to set the flash power. All I get on the flash unit and on the camera screen is ev adjustment. I want to be able to use flash remotely and shoot using flash power adjustments.
