Hello, I'm a total newb with external speedlite photography.
Can anyone help me get my external flash going with my camera?
I just got a Nikon D750 with a Sigma 24-105mm F4 lens.
And I got a Yongnuo YN685 Speedlite.
I do not have a trigger.
I am trying to have the Nikon do the light flash, where the flash sets off the external YN685 flash.
Whatever that process is called? Is there a name for it?
I set the YN685 to "603 Slave", by holding down the "Mode" button, and then turning the dial to "603 Slave". Then pressed the middle "set" button. The redlights started flashing indicating it was ready.
I set the Nikon D750 to Commander.
Pressed "Menu > Custom Settings > Bracketing Flash > Flash cntrl for built-in Flash > Commander Mode Group A and Channel 1.
Initially this option wasn't available to me, as I had not turned the left dial to "M" on the camera.
I did not know this -- again, i'm a newb with this camera.
Popped up the D750's built-in flash.
Took a picture, and I got a black picture.
The built-in D750 flash did go off, but slightly less than full-blast.
And the external YN685 did NOT fire off.
I need help getting this to work.
